Pisa Online Seminars - Atul Shekhar (Tuesday, March 9 at 16:00)
by Giacomo Filippo Di Gesu 02 Mar '21

02 Mar '21

Dear colleagues, I would like to invite you to the following online seminar organized by the Probability group of the University of Pisa. The talk 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, March 9, 16:00 Speaker: Atul Shekhar (Université Lyon 1) Title: On the fixed points of Branching Brownian motion Abstract: We consider a particle system on the real line in which each particle evolves into many particles via independent Branching Brownian motions. Under a very mild natural assumption, we give a full characterisation of the fixed points of this particle system. This result is motivated by an earlier work of T. Liggett on particle systems without branching. Further motivations come from the close connection between the Branching Brownian motion and the two dimensional Gaussian free field. This talk is based on a joint work with Christophe Garban and Xinxin Chen. ************************ Giacomo Di Gesù Dipartimento di Matematica Università di Pisa Largo Bruno Pontecorvo 5 56127 - Pisa, Italy giacomo.digesu(a)unipi.it<mailto:giacomo.digesu@unipi.it> https://sites.google.com/site/giacomodigesu/

AMaMeF: update on the 2021 conference in Padova
by Tiziano Vargiolu 02 Mar '21

02 Mar '21

Dear all, we hope that this message finds you well. This message is an update on the 10th general AMaMeF (Advanced Mathematical Methods for Finance) conference, scheduled on June 22-25, 2021, at the University of Padova (Italy). In agreement with the AMaMeF steering committee, we decided to keep the conference on the scheduled dates. Obviously, the current pandemic situation, travel restrictions and the uncertainty of the near future prevent us from organising a conference and the accompanying social events in the style of the good old days. For this reason, we are planning a conference in a hybrid format, with the presence of a limited number of participants and with the option of rapidly switching to a fully online conference, if the hybrid format will turn out to be unfeasible. All of the plenary speakers confirmed their willingness to participate to the conference, and most of them will be present, if possible. The Call for contributed sessions and talks will be announced and opened very soon. Please visit the conference webiste for more detailed informations and constant updates: https://events.math.unipd.it/AMAMEF2021/ Best wishes Tiziano -------------------------------------------------------------------------- Tiziano Vargiolu Dipartimento di Matematica Phone: +39 049 8271383 Universita' di Padova Fax: +39 049 8271428 Via Trieste, 63 E-mail: vargiolu(a)math.unipd.it I-35121 Padova (Italy) WWW: http://www.math.unipd.it/~vargiolu --------------------------------------------------------------------------

Fwd: [owps] One World Probability Seminar Thursday February 25, 2021

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.
