(Corrected) Pisa Online Seminars - Alessandra Cipriani and Trishen Gunaratnam (Tuesday, Nov. 24 at 14:00 and 15:00)
by Giacomo Filippo Di Gesu 19 Nov '20

19 Nov '20

I mistakenly sent you twice the same abstract yesterday. Please find below the correct version. Best, Giacomo **************** Dear colleagues, I would like to announce the following online seminar organized by the Probability group of the University of Pisa. The talks will be accessible under the link Click here to join the meeting<https://teams.microsoft.com/l/meetup-join/19%3a17115d7f6ef44c5e91974362906c…> Tuesday, Nov. 24, 14:00 Speaker: Alessandra Cipriani (TU Delft) Title: Some properties of the discrete membrane model Abstract: The discrete membrane model (MM) is a random interface model for separating surfaces that tend to preserve curvature. It is a very close relative of the discrete Gaussian free field (DGFF), for which instead the most likely interfaces are those preserving the mean height. However working with the two models presents some key differences, in that in the MM the shape is driven by the biharmonic operator, while the DGFF is essentially a Gaussian perturbation of harmonic functions. In particular, a lot of tools (electrical networks, random walk representation of the covariance) are available for the DGFF and lack in the MM. In this talk we will review some basic properties of the MM, and we will investigate a random walk representation for the covariances of the MM and what it can bring forth in terms of scaling limits of its extremes. This talk is based on joint works, partly ongoing, with Biltu Dan, Rajat Subhra Hazra (ISI Kolkata) and Rounak Ray (TU/e). Tuesday, Nov. 24, 15:00 Speaker: Trishen Gunaratnam (Université de Genève) Title: Phase transitions for $\phi^4_3$ Abstract: In this talk I will discuss recent results obtained in joint work with Ajay Chandra (Imperial) and Hendrik Weber (Bath) about the large-scale behaviour of the $\phi^4_3$ Euclidean field theory. In particular, I will discuss a surface order large deviations estimate for the average magnetisation at sufficiently low temperatures in large but finite volumes. This is a manifestation of phase transition, which is well-known for this model. As a byproduct of this, one can quantify a breakdown of ergodicity for the Glauber dynamics of this model - given by the dynamical $\phi^4_3$ singular SPDE - for sufficiently low temperatures in the infinite volume limit.

Padova Online Seminar by Alessandro Zocca (Vrije Universiteit Amsterdam) [Friday, Nov. 27 at 11.30]
by alessandra bianchi 17 Nov '20

17 Nov '20

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on November 27 at 11.30 by the zoom platform. ________________________________________________________ Speaker: Alessandro Zocca (Vrije Universiteit Amsterdam) Title: Power grids as stochastic networks: emergent failures and mitigation strategies 27 NOVEMBER (Friday) - 11:30 zoom link: TBA (available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: Power grids are one of the most complex and critical networks in modern-day society, which we expect to function reliably at all times. The increasing adoption of renewable energy sources such as solar panels and wind turbines, introduces a massive amount of uncertainty into power grids, due to their intrinsically intermittent and highly variable nature. In this talk I will give an overview of my current research, which aims to develop new mathematical tools to analyze power grids and their performance in the presence of uncertainty. Stochastic fluctuations of the power injections affect line flows and phase angle frequencies, and, when amplified by correlations and network effects, they can cause failures and possibly blackouts. Large deviations techniques and ad-hoc MCMC methods allow us to better understand how these emergent failures occur and to estimate their likelihood. A peculiar feature of cascading failures in power grids is that they propagate nonlocally, making the control and mitigation of these failures extremely hard. I will illustrate a novel strategy we devise using tools from graph theory, spectral clustering, and optimization to mitigate the impact of line failures and their non-local propagation. -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

Dear all, We are glad to announce the next DEMS webinar: Wednesday, 18th November 2020, time 13.00 (CET). link to attend: https://unimib.webex.com/unimib/onstage/g.php?MTID=eadc0aefcf2b20a4d5b65dfc… The speaker is *François Caron*, Department of Statistics, University of Oxford (UK). ******************************************************* *TITLE*. *A unified construction for series representations and finite approximations of completely random measures* *ABSTRACT*. Infinite-activity completely random measures (CRMs) have become important building blocks of complex Bayesian nonparametric models. They have been successfully used in various applications such as clustering, density estimation, latent feature models, survival analysis or network science. Popular infinite-activity CRMs include the (generalized) gamma process and the (stable) beta process. However, except in some specific cases, exact simulation or scalable inference with these models is challenging and finite-dimensional approximations are often considered. In this work, we propose a general and unified framework to derive both series representations and finite-dimensional approximations of CRMs. Our framework can be seen as a generalization of constructions based on size-biased sampling of Poisson point process [Perman et al., 1992]. It includes as special cases several known series representations and finite approximations as well as novel ones. In particular, we show that one can get novel series representations for the generalized gamma process and the stable beta process. We show how these constructions can be used to derive novel algorithms for posterior inference, including a generalization of the slice sampler for normalized CRMs mixture models introduced by Griffin and Walker [2011]. We also provide some analysis of the truncation error.

WEBINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Joint initiative with MIDAS COMPLEX MODELING RESEARCH NETWORK <http://midas.mat.uc.cl/network> Venerdi 20 Novembre 2020, alle ore 17:00, si terrà il seguente webinar: ------------------------------------------------ Speaker: Didong Li (Princeton and UCLA) Title: Learning & Exploiting Low-Dimensional Structure in High-Dimensional Data Abstract: Data lying in a high-dimensional ambient space are commonly thought to have a much lower intrinsic dimension. In particular, the data may be concentrated near a lower dimensional subspace or manifold. There is an immense literature focused on approximating the unknown subspace and the unknown density, and exploiting such approximations in clustering, data compression, and building of predictive models. Most of the literature relies on approximating subspaces and densities using a locally linear, and potentially multi-scale, dictionary with Gaussian kernels. In this talk, we propose a simple and general alternative, which instead uses pieces of spheres, or spherelets, to locally approximate the unknown subspace. I will also introduce a curved kernel called the the Fisher–Gaussian (FG) kernel which outperforms multivariate Gaussians in many cases. Theory is developed showing that spherelets can produce lower covering numbers and mean square errors for many manifolds, as well as the posterior consistency of the Dirichlet process mixture of FG kernels. Results relative to state-of-the-art competitors show gains in ability to accurately approximate the subspace and the density with fewer components and parameters. Time permitting, I will also present some applications of spherelets, including classification, geodesic distance estimation and clustering. ------------------------------------------------ Join Zoom Meeting https://us02web.zoom.us/j/81832398725?pwd=QUl5eXNIM0xFSXNjTG9IaFZkL0lCQT09 <https://www.google.com/url?q=https%3A%2F%2Fus02web.zoom.us%2Fj%2F8183239872…> Meeting ID: 818 3239 8725 Passcode: 768768 Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats <http://www.carloalberto.org/stats> nell’ambito del Complex Data Modeling Research Network midas.mat.uc.cl/network <http://midas.mat.uc.cl/network> in collaborazione con il Collegio Carlo Alberto.

Seminario di Isaia Nisoli lun 16 nov 2020 (DinAmici & Milano Bicocca)
by Francesco Caravenna 11 Nov '20

11 Nov '20

Nell’ambito del ciclo "DinAmicI: Another Internet Seminar" (https://www.dinamici.org/dai-seminar/) Isaia Nisoli (Institute of Mathematics-Rio de Janeiro) terrà un seminario online la settimana prossima. Seguono i dettagli: ******************************************** Data: Lunedì 16 novembre 2020, h 14:00 Titolo: A simple system presenting Noise Induced Order Abstract: In this talk I will present a family of one dimensional systems with random additive noise such that, as the noise size increases, the Lyapunov exponent of the stationary measure transitions from positive to negative. This phenomena is known in literature as Noise Induced Order, and was first observed in a model of the Belosouv-Zhabotinsky reaction and its existence was proven only recently by Galatolo-Monge-Nisoli. In the talk I will show how this phenomena is strictly connected with non-uniform hyperbolicity and the coexistence of regions of expansion and contraction in phase space; the result is attained through a result on the continuity of the Lyapunov exponent of the stationary measure with respect to the size of the noise.

To illustrate it, we consider the evolution of the magnetization in the Ising model and the dynamics of the condensate in critical zero-range processes. (15:00-16:00 UTC) Insuk Seo (Seoul National University Title: Metastability of stochastic interacting systems Abstract: In this second presentation regarding the metastability of random dynamical systems, we focus on two specific models to understand how the general methodologies introduced in the first presentation can be applied. The first model is the Ising model on a finite, fixed, and large lattice without an external field at very low temperatures. We explain how the potential theory can be effectively employed for analyzing the said model, whose saddle between ground states comprises a large set of configurations with complicated structure. The second model is the zero-range process with sticky interaction. We elucidate how various approaches can be applied for handling the non-reversibility or the criticality associated with the stickiness of particles. The study on the Ising model is a collaboration with S. Kim, and the study on the zero-range process is a collaboration with C. Landim and D. Marcondes. ------------------------------------------------ The zoom link will appear the day before on the OWPS website: https://www.owprobability.org/one-world-probability-seminar <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.owpro…> It can also be directly accessed through the link below: https://impa-br.zoom.us/j/93849865809?pwd=Nzg5TTJOai9KQkRXS0ROcHNjL2JVZz09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fimpa-br.z…> Please feel free to circulate this email.

Pisa Online Seminars - Giovanni Conforti and Ruojun Huang (Tuesday, Nov. 10 at 14:00 and 15:00)
by Giacomo Filippo Di Gesu 09 Nov '20

09 Nov '20

Dear colleagues, I would like to announce the following online seminar organized by the Probability group of the University of Pisa. The talks will be accessible under the link Click here to join the meeting<https://teams.microsoft.com/l/meetup-join/19%3a17115d7f6ef44c5e91974362906c…> Best regards, Giacomo *********** Tuesday, Nov. 10, 14:00 Speaker: Giovanni Conforti (École Polytechnique) Title: A probabilistic approach to convex entropy decay for Markov chain Abstract: A powerful technique to quantify the trend to equilibrium and the best constants in the associated functional inequalities for diffusions on Riemannian manifolds consists in establishing convexity estimates for the relative entropy via the so called Gamma calculus. In order to adapt these ideas to the context of discrete Markov chains several notions of discrete curvature have been recently introduced and used to obtain concrete lower bounds for the logarithmic Sobolev constant in a number of situations. However, the picture is not fully clear yet and several natural questions remain unanswered. In this talk, I will present a more probabilistic approach to convex entropy decay which relies on the notion of coupling rates to bypass or replace discrete Böchner identities. If time allows, I will show how this approach produces explicit lower bounds in non perturbative setting, thus going beyond the weak-interaction/low high temperature regime. Tuesday, Nov. 10, 15:00 Speaker: Ruojun Huang (Scuola Normale Superiore) Title: Averaging principle and random growth Abstract: Motivated by questions in reinforced random walks and the asymptotic shape of their range, we study a simplified model of random growth in the continuum. In this model, random sets grow by increment of small bumps at the boundary, driven by a particle that is confined to move in its interior, reinforced by the last location of domain's increment. We prove scaling limit of the growing domain to an infinite dimensional ODE, when the bump size is sent to zero. We deduce a macroscopic shape theorem for the growing domain with fixed bump size, as time tends to infinity. Joint work with Amir Dembo, Pablo Groisman, and Vladas Sidoravicius.

| Dear colleagues, |||| LTI@UniTO (www.carloalberto.org/lti) is pleased to invite you to the following Webinars in Finance: *9 NOVEMBER 2020 | h. 12:45-13:45* || | *“Corporate foreign bond issuance and interfirm loans in China”* |** || *Ugo Panizza (Graduate Institute of International and Development Studies, Geneva)* Abstract: We use firm-level data to analyze international bond issuance by Chinese non-financial corporations. The interest rate differential between domestic and foreign interest rates increases the likelihood of dollar bond issuance by risky firms. Most strikingly, risky firms do more interfirm lending than non-risky firms. This lending rose significantly after the authorities sought to restrict the financial activities of risky firms in 2008-09. Risky firms try to boost profitability by engaging in speculative activities that mimic the behavior of financial institutions while escaping prudential regulation that limits risk-taking by financial firms. /Joint with Yi Huang and Richard Portes/ *Zoom Link https://us02web.zoom.us/j/86538325685?pwd=SlFtZTlxQVI2cktZanhPOUlFWGVjQT09 <https://us02web.zoom.us/j/86538325685?pwd=SlFtZTlxQVI2cktZanhPOUlFWGVjQT09> * Meeting ID: 865 3832 5685 Passcode: 460794 |(Attendance is limited to maximum 100 participants)| For more information https://www.carloalberto.org/event/ugo-panizza/ ------------ *11 NOVEMBER 2020 | h. 15:00 - 16:15* || *Sergei Glebkin (INSEAD)* || |*“Simultaneous Multilateral Search”*| || Abstract: This paper studies simultaneous multilateral search (SMS) in over-the-counter (OTC) markets: when searching, an investor contacts several potential counterparties and then trades with the one offering the best quote. Search intensity (how frequently one can search) and search capacity (how many potential counterparties one can contact) affect market qualities differently. Contrasting SMS to bilateral bargaining (BB), the model shows that investors might favor BB over SMS if search intensity is high or in distress. Such preference for BB hurts allocative efficiency and suggests an intrinsic hindrance in the adoption of all-to-all and request-for-quote type of electronic trading in OTC markets. /Joint with Bart Yueshen (INSEAD)./ *Zoom Link https://us02web.zoom.us/j/81064877787?pwd=Z2grNzZwbGtXd25yakR3NkU4cFNFZz09 <https://us02web.zoom.us/j/81064877787?pwd=Z2grNzZwbGtXd25yakR3NkU4cFNFZz09>* Meeting ID: 810 6487 7787 Passcode: 733237 ||(Attendance is limited to maximum 100 participants)|| For more information https://www.carloalberto.org/event/sergei-glebkin/ Best regards, Luca Regis | -- Luca Regis Associate Professor Department of Economics and Statistics (ESOMAS) University of Torino sites.google.com/view/lucaregis Office: +39 011 670 6065 www.carloalberto.org/lti || ||

We focus here on 2-scale convergence for random walks. In the first talk we aim to provide a gentle introduction to 2-scale convergence for random walks in a random environment with symmetric rates. Using the Palm theory of random measures we discuss ergodicity issues at a 2-scale level. We then introduce a basic difference calculus and define 2-scale convergence of functions and gradients, corresponding to an enforced averaging property. Finally we discuss the fundamental compactness and structure theorem for bounded families of H^1-functions, where geometrical issues of square integrable forms and the homogenized matrix emerge. In the second talk we discuss some applications of the above 2-scale convergence for random walks in a random environment. A first one is given by the invariance principle of random walks on the supercritical percolation cluster of P. Mathieu and A. Piatnitski. We then discuss more in detail applications to the homogenization of the massive Poisson equation associated with the random walk, which also enters in the derivation of the hydrodynamic limit of exclusion and zero range processes. Finally, we discuss applications to random resistor networks, in particular to the conductance model and the Miller-Abrahams one associated to Mott variable range hopping in amorphous solids. ------------------------------------------------ The zoom link will appear the day before on the OWPS website: https://www.owprobability.org/one-world-probability-seminar <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.owpro…> It can also be directly accessed through the link below: https://impa-br.zoom.us/j/94248802467?pwd=VlVQQzlsbjdKTHplRlRGbGlJRG5YUT09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fimpa-br.z…> Please feel free to circulate this email.
