Padova Seminars in Probability and Finance - Maurizia Rossi (Università Milano Bicocca)
by alessandra bianchi 18 Nov '22

18 Nov '22

Dear Colleagues, We would like to invite you to the following seminar that will take place on November 25 at 15.30. The seminar will be held in person and online via the Zoom platform. The organizers, Alessandra Bianchi, Giorgia Callegaro, Marco Formentin _____________________________________________________ *Speaker*: Maurizia Rossi (Università Milano Bicocca) *Title*: Gaussian Kinematic Formulas for Random Spherical Harmonics *Date and time*: Friday, NOVEMBER 25 at 15.30 *Place*: room 2AB40 at the Department of Mathematics, University of Padova *Zoom link*: https://unipd.zoom.us/j/83301000752 (meeting ID: 833 0100 0752) available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ *Abstract*: In this talk we investigate the geometry of random spherical harmonics (Gaussian Laplace eigenfunctions on the round sphere). In particular we study the distribution, for large eigenvalues, of Lipschitz-Killing Curvatures (LKCs) of their excursion sets at any threshold. The main result we discuss is an asymptotic equivalence, in mean-square, between these functionals and the L2-norm of the random eigenfunction times a suitable map of the threshold (that vanishes at zero). This formula allows one to determine limiting distribution, correlation phenomena and moderate deviations for these LKCs, and generalizes - in the case of random spherical harmonics - those obtained by Adler and Taylor for their expected value. If time permits, we digress slightly to investigate the local geometry of spin spherical random fields, that is, random sections of the spin line bundles of the sphere. This talk is mainly based on a number of joint works on random spherical harmonics with V. Cammarota, D. Marinucci and I. Wigman + a recent work on spin random fields written jointly with A. Lerario, D. Marinucci and M. Stecconi. -- 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/

LUISS math seminar - Regis Chenavaz, November 24, 2022 (& link)
by Sara 17 Nov '22

17 Nov '22

Dear all, I am pleased to announce the next seminar in our series. On Thursday 24 at 12:00 in Room AT03, prof. Chenavaz - KEDGE Business School - will talk about: *The Veblen effect* The increase of demand in price, an exception to the law of demand, is known as the Veblen effect. In Luiss' seminar we present two works on the Veblen effect. In the first (published) work, we consider a profit maximizing monopoly which by means of advertising impacts the price-demand relationship. We show that advertising and goodwill play an important role in making the Veblen effect more prevalent than expected. By employing optimal control theory, we capture the evolution of the variables over time, which may exhibit the Veblen effect where price and demand move in the same direction. In the second (in progress) work, we investigate the price-demand relationship, when price is the sole control variable. We assume that a higher price (control variable) enhances brand-image (state variable) translating into more sales. Using optimal control theory, we look at the conditions for the Veblen effect to happen. Eventually, a more comprehensive understanding of firms’ decisions driving the Veblen effect has a promising impact on securing long-term profits. *Here are the credentials and the link for online participation:* Aula AT03: https://luiss.webex.com/luiss/j.php?MTID=mb27b65706219cee49db438fbecdd0f3d *User*: *w_guest(a)luiss.it <w_guest(a)luiss.it>* *Password*: ihPmCRdl76Q -- Sara Biagini, Professor of Mathematical Finance Department of Economics and Finance LUISS Guido Carli https://www.luiss.it/ Address: Viale Romania, 32 - 00197 Roma Web: http://sites.google.com/site/sarabiagini/

Dear Colleagues, We would like to invite you to the following SPASS <https://sites.google.com/unipi.it/spass> seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *A diagram-free approach to the stochastic estimates in regularity structures* by Markus Tempelmayr (Max Planck Institute, Leipzig) The seminar will take place in person on *TUE, 15.11.2022 at 14:00* in Collegio Puteano, Scuola Normale Superiore di Pisa and streamed online here <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- Abstract: *A diagram-free approach to the stochastic estimates in regularity structures* *We present an alternative point of view on Hairer's regularity structures that is well suited, but not restricted to, quasilinear singular SPDEs. Guided by symmetries of the equation, we approach the counterterm top-down rather than bottom-up. The model, which captures the local solution behaviour, is indexed by partial derivatives w.r.t. the nonlinearity. This allows for efficient bookkeeping and automated (inductive) proofs. The main assumption on the driving noise is a spectral gap inequality, which complements well the BPHZ choice of renormalization.This is joint work with Pablo Linares, Felix Otto, and Pavlos Tsatsoulis.*

de Finetti Risk Seminar - November 2022
by Emanuela Rosazza Gianin 15 Nov '22

15 Nov '22

On behalf of the Scientific Committee of the "B. de Finetti Risk Seminars, Milano Lectures on the Mathematical Theory of Economics and Finance”, we are glad to invite you to participate at the following Lecture: Cosimo Andrea Munari University of Zurich, Switzerland Title: Market-consistent pricing with acceptable risk Abstract: We study the range of prices at which a rational agent should contemplate transacting a financial contract outside a given securities market. Trading is subject to nonproportional transaction costs and portfolio constraints and full replication by way of market instruments is not always possible. Rationality is defined in terms of consistency with market prices and acceptable risk thresholds. We obtain a direct and a dual description of market-consistent prices with acceptable risk. The dual characterization requires an appropriate extension of the classical Fundamental Theorem of Asset Pricing where the role of arbitrage opportunities is played by good deals, i.e., costless investment opportunities with acceptable risk-reward tradeoff. In particular, we highlight the importance of scalable good deals, i.e., investment opportunities that are good deals regardless of their volume. The talk is based on joint work with Maria Arduca (LUISS Rome). LOCATION: The seminar will be held on *November 30, *2022 at *18.00,* Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano. A light reception will take place at 17.45. Scientific Committee Prof. Simone Cerreia-Voglio (Univ. Bocconi) Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ.

LUISS math seminar - Huyen Pham, November 8, 2022 (& link)
by Sara 14 Nov '22

14 Nov '22

Dear all, I am pleased to announce the next seminar in our series. *Speaker: Huyen Pham, Université Paris Cité* Abstract. With the emergence of new online channels and information technology, digital advertising tends to substitute more and more to traditional advertising by offering the opportunity to companies to target the consumers/users that are potentially interested by their pro\-ducts or services. We introduce a continuous time model for the study of optimal bidding strategies associated to different types of advertising, namely, commercial advertising for triggering purchases or subscriptions, and social marketing for alerting population about unhealthy behaviours (anti-drug, vaccination, road-safety campaigns). Our framework encodes users online behaviours via their web-browsing at random times, social interactions in a large population of users, and the targeted advertising auction mechanism widely used on Internet. We address the attribution problem of how to efficiently diffuse advertising information by means of digital channels in order to generate conversion. Our main results are to provide semi-explicit formulas for the optimal value and bidding policy in various contexts of commercial advertising and social marketing. We show sensitivity properties of the solution with respect to model parameters, and analyse how the different sources of digital information accessible to users including the social interactions affect the optimal bid for advertising auctions. We also study how to efficiently combine targeted advertising and non-targeted advertising mechanisms. Finally, some classes of examples with fully explicit formulas are derived. The seminar will be held in Room 106, - viale Romania 32, Roma.

Depending on the value of the Hurst parameter H, the resulting equation is pathwise viewed as an ordinary (H>1), Young (H in (1/2, 1)) or rough (H in (1/3, 1/2)) differential equation. In all three regimes we show regularisation by noise phenomena by proving the strongest kind of well-posedness for equations with irregular drifts: strong existence and path-by-path uniqueness. In the Young and smooth regime H>1/2 the condition on the drift coefficient is optimal in the sense that it agrees with the one known for the additive case. In the rough regime (H in(1/3,1/2)) we assume positive but arbitrarily small drift regularity for strong well-posedness, while for distributional drift we obtain weak existence. This is a joint work with Máté Gerencsér. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/87612328974?pwd=OFZnMGxrWll6ZE9uVHdjQTkzYUN3Zz09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 18 Novembre 2022, alle ore 11.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Rao Vinayak* (Purdue University USA) Title: *Differential Privacy and Bayesian Computation: Two Vignettes* Abstract: Differential privacy (DP) protects privacy by introducing additional randomness into a recorded dataset. It comes with strong theoretical guarantees, and has become a state-of-the-art framework for privacy protection. In this talk, we consider two complementary challenges raised by DP. In the first part, we recognize that implementing DP mechanisms require sampling algorithms like MCMC or rejection sampling. In these instances, the algorithm runtime itself can leak privacy, so that practical implementations fail to maintain the original theoretical guarantees. To address this, we propose modifications to rejection and adaptive rejection sampling algorithms, with varying assumptions, to protect against timing attacks. In the second part, we focus on a more traditional statistics problem related to differential privacy: given access to only the privatized data, how to perform valid statistical inference on parameters underlying the confidential data. Here, the likelihood function of the privatized data requires integrating over the large space of confidential databases and is typically intractable, resulting, in Bayesian settings, in a posterior distribution that is doubly intractable. We propose a generic MCMC framework which is applicable to a wide range of statistical models and privacy mechanisms. Our MCMC algorithm is a simple wrapper that extends MCMC algorithms for the unobserved confidential data to settings where the data is privatized. Our approach translates privacy guarantees of the DP mechanism into mixing properties of the MCMC algorithm, while maintaining the same order of computational cost as the algorithm for non privatized data. We illustrate the efficacy and applicability of both our ideas on several examples. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/87612328974?pwd=OFZnMGxrWll6ZE9uVHdjQTkzYUN3Zz09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Dear all, we are glad to inform you that the Applied Bayesian Statistics school is back! ABS23 will be held in Firenze on June, 12-16, 2023. The school is organised by CNR IMATI (Institute of Applied Mathematics and Information Technologies at the Italian National Research Council in Milano), this year in cooperation with the Florence Center for Data Science and the Department of Statistics, Computer Science and Applications at the University of Firenze. The topic will be BAYESIAN CAUSAL INFERENCE. The lecturer will be FAN LI (Duke University, https://scholars.duke.edu/person/fli) with the support by researchers at the University of Firenze. If interested, you can register on the school website: http://www.mi.imati.cnr.it/conferences/abs23/ REGISTRATION is now open but payments will be possible (by bank transfer or credit card) only after January, 30, 2023. If you are interested in the school but unwilling to register for the moment, please send an email to abs23(a)mi.imati.cnr.it and we will send you updates and reminders. As in the past (since 2004), there will be a combination of theoretical and practical sessions, along with presentations by participants about their work (past, current and future) related to the topic of the school. OUTLINE: The aim of this course is to introduce the fundamental concepts and the state-of-the-art methods for causal inference under the potential outcomes framework, with an emphasis on the Bayesian inferential paradigm. Topics will cover randomized experiments, common methods for observational studies, such as propensity score, matching, weighting and doubly-robust estimation, heterogeneous treatment effects, sensitivity analysis, instrumental variables, principal stratification, panel data methods, and longitudinal treatments. Recent advances related to high dimensional analysis and machine learning will be naturally incorporated into the discussion. All methods will be illustrated via real world case studies. We hope you will be interested in the school and we would like to meet you in Firenze next year. We invite you also to share the information with people potentially interested. Best regards Elisa Varini and Fabrizio Ruggeri Executive Director and Director of ABS23

Seminar: Riccardo Maffucci at Tor Vergata
by mic sal 09 Nov '22

09 Nov '22

Dear all, next Thursday, May 5th, Riccardo Maffucci (EPFL) will give a seminar about "Distribution of nodal intersections for random waves". Abstract: This work is in collaboration with Maurizia Rossi. Random waves are Gaussian Laplacian eigenfunctions on the 3D torus. We investigate the length of intersection between the zero (nodal) set, and a fixed surface. Expectation, and variance in a general scenario are prior work. In the generic setting we prove a CLT. We will discuss (smaller order) variance and (non-Gaussian) limiting distribution in the case of ’static’ surfaces (e.g. sphere). Under a certain assumption, there is asymptotic full correlation between intersection length and nodal area. The seminar will take place in Aula De Blasi, Università Tor Vergata, at 16h00. We encourage in-person partecipation, but should you unable to come here is the link to the event on Teams: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw… The seminar is part of the Excellence Project Math@TOV.

Università di Napoli Federico II Dipartimento di Matematica e Applicazioni Avviso di Seminario Il giorno 15 novembre p.v. alle ore 16 nell'aula G al III livello, la Dott.ssa Fatemeh Hooti, assegnista di ricerca presso il Dipartimento di Matematica e applicazioni, terrà un seminario dal titolo "Optimal Extended Warranty Length With Limited Number of Repairs in The Warranty Period". Abstract: Due to the advances in the technology of complex industrial systems, the consumers of these products are always worried about the costs of purchasing and maintenance of them. Manufacturers also want to increase the number of customers for their products and profit from sales. However, the reliability of engineering systems can be affected by several factors, so the occurrence of failure and the need to repair and maintain these products after their production is inevitable. In this case, the discussion of the warranty of the manufactured products plays an important role in assuring the consumers and also reducing the damages to producers and customers. The policies introduced for the warranty of engineering systems are divided into two categories one-dimensional and two-dimensional warranty based on the number of variables that are aimed at optimizing the fixed and random costs of the project. Also, so far, several cost functions have been considered to check and reduce these costs. In the talk, a policy plan is proposed for the warranty length of a repairable system which consists of a number of minimal repairs and duration of service?. ?For this purpose?, ?two total expected costs of the manufacturer are considered as the objective of the optimization model, and the conditions for finding unique optimal solutions are investigated?.
