Fwd: [owps] One World Probability Seminar Thursday February 25, 2021
by Faggionato, Alessandra 24 Feb '21

24 Feb '21

Buongiorno, vi inoltro l'annuncio del OWPS di domani. Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 24 feb 2021 alle ore 12:25 Subject: [owps] One World Probability Seminar Thursday February 25, 2021 To: <owps(a)lists.bath.ac.uk> Tomorrow's speakers in the One World Probability Seminar are (Note: all times are in UTC. *Due to time changes, you should check what that translates to in your location*) ------------------------------------------------ (14:00-15:00 UTC) Speaker: Fredrik Viklund (KTH) Title: Interplay between Dirichlet and Loewner energies: cutting-welding operations and foliations by Weil-Petersson quasicircles - Part 1 Abstract: The Loewner energy is a Mobius invariant deterministic quantity attached to Jordan curves in the plane. One way in which it arises is as a large deviations rate function for the Schramm-Loewner evolution with small parameter. A curve has finite Loewner Energy if and only if it is a Weil-Petersson quasicircle, a class of curves that in the last decades has received significant attention by both physicists and mathematicians, but only very recently by probabilists. The Loewner-Kufarev energy is a dual quantity attached to certain continuous families of Jordan curves, which arises in the context of large deviations of SLEs with large parameter. We will survey recent joint works (and beyond) that describe the interplay between these energies (and the Weil-Petersson quasicircles) with the usual Dirichlet energy on the plane. The results are closely related to recent ideas and developments in Random Conformal Geometry but proofs are purely analytic. In the first talk, we begin by presenting background material and a survey of properties and characterisations of Weil-Petersson quasicircles. We then discuss interactions between Weil-Petersson quasicircles with ambient Dirichlet class functions via cutting and conformal welding operations as well as interpretations in terms of "flow-lines". At the end we will present a "dictionary" that relates these statements with ideas in Random Conformal Geometry. (15:00-16:00 UTC) Speaker: Yilin Wang (MIT) Title: Interplay between Dirichlet and Loewner energies: cutting-welding operations and foliations by Weil-Petersson quasicircles - Part 2 Abstract: The main topic of the second talk is the Loewner-Kufarev energy and corresponding families of Weil-Petersson quasicircles. We will indicate how to associate to such a foliation a (geometric) "winding function" on the plane whose Dirichlet energy equals the (analytic) Loewner-Kufarev energy. This duality entails several interesting results: for example, the Loewner-Kufarev Energy is in fact reversible and we obtain a new characterisation of Weil-Petersson quasicircles. We will end by discussing further implications and open problems. *Main references:*F. Viklund, Y. Wang: Interplay between Loewner and Dirichlet energies via conformal welding and flow-lines, Geom.

Seminari Gruppo PRISMA
by c.ceci＠unich.it 22 Feb '21

22 Feb '21

Buongiorno a tutti, abbiamo il piacere di annunciare il secondo appuntamento del ciclo mensile di seminari online promosso dal Gruppo UMI PRISMA. Lunedi’ 1 marzo 2021, ore 16-18 Alessandra Faggionato Titolo: Random resistor networks and Mott’s variable range hopping Abstract: Random resistor networks allow to study electron transport indisordered systems. By means of stochastic homogenization one can characterize the infinite volume effective conductivity in terms of the homogenized matrix of suitable discrete Poisson equations. We will then focus on the low temperature behavior of the random conductance model and the Miller-Abrahams random resistor network. The latter models the so-called Mott’s variable range hopping, a fundamental transport mechanism in disordered solids in the regime of strong Anderson localization. We will discuss its percolative properties and show how homogenization, percolation and scaling arguments lead to Mott’s law. (For the percolation part, the talk is based on joint works with H.A. Mimun). Elisabetta Candellero Titolo: Competition processes on hyperbolic non-amenable graphs Abstract: We consider two first-passage percolation processes, FPP_1 and FPP_\lambda, spreading with rates 1 and \lambda respectively, on a graph G with bounded degree. FPP_1 starts from a single source, while the initial configuration of FPP_\lambda consists of countably many seeds distributed according to a product of iid Bernoulli random variables of parameter \mu on the set of vertices. This model is known as "First passage percolation in a hostile environment" (FPPHE), and was introduced by Stauffer and Sidoravicius as an auxiliary model for investigating a notoriously challenging model called Multiparticle Diffusion Limited Aggregation. We consider several questions about FPPHE, focusing on the case when G is a non-amenable hyperbolic graph. This talk is based on joint works with Alexandre Stauffer.

Padova Online Seminar by Luca Avena (Leiden University) [Friday, Feb. 26 at 14.30]
by alessandra bianchi 19 Feb '21

19 Feb '21

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on February 26 at 14.30 by the zoom platform. ________________________________________________________ Speaker: Luca Avena (Leiden University) Title: Node immunization in networks: a scalable searching algorithm based on random rooted forests 26 FEBRUARY (Friday) - 14:30 zoom link: TBA available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: We are interested in the so-called multiple-node immunization for complex networks under attack of a viral agent. The latter is a hot topic in network science and it consists of identifying and removing a set of nodes of a given size in a graph to maximally impede the agent spread. Several approaches have been proposed in the literature based on numerical and theoretical insights on how classical models for virus spread (so-called compartmental models) evolve on graphs. Based on the stability analysis of these compartmental models, the maximal eigenvalue of the adjacency matrix of the graph has been proposed as a measure for how resilient the network is. Thus one of the most common approaches for immunization consists in identifying the set of nodes of a given cardinality, for which the reduced network, obtained by removing these nodes, has minimal largest eigenvalue. This optimization problem turns out to be a computationally hard problem in the well known NP class and the available exact or proxy algorithms offer good solutions and performances only for small data sets. We propose a novel randomized flexible method to efficiently identify these sets of nodes based on random walk kernels and random rooted forests. We explain the theoretical results underlying the method, and present experimental results where we test method and performances on classical synthetic and real-world benchmarks.
