Padova Online Seminar by Paolo Dai Pra (Università di Verona) [Friday, June 25 at 14.30]

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on June 25 at 14.30 by the zoom platform. ________________________________________________________ Speaker: Paolo Dai Pra (Università di Verona) Title: The social dilemma of stubborness vs. herding in social decisions: a mean field (game) model. 25 JUNE (Friday) - 14:30 zoom link: TBA available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: We study a mean field game in continuous time over a finite horizon, T, where the state of each agent is binary and where players base their strategic decisions on two, possibly competing, factors: the willingness to align with the majority (herding) and the aspiration of sticking with the own type (stubbornness). While the corresponding N-player game possesses a unique Nash equilibrium, the mean field game has a variety of equilibria and phase transitions. The large N limit of the unique equilibrium of the N-player game selects one equilibrium of the mean field game; this selection appears to be highly nontrivial and will be discussed mostly on the base of simulations. -- 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/

Seminar announcement Thursday 24 - Limit theorems for exponential random graphs (dr. Elena Magnanini)
by Gianmarco Bet 14 Jun '21

14 Jun '21

Dear colleagues, On June Thursday 24 at 15:30, dr. Elena Magnanini (Università degli Studi di Padova) will give a virtual seminar “in Florence”, to which you are all invited. You can find title and abstract below. Title: Limit theorems for exponential random graphs Abstract: In the present talk we focus on the derivation of some asymptotic properties for the family of exponential random graphs. This model can be seen as the generalization of the dense Erdӧs-Rényi random graph and follows the statistical mechanics approach of defining a Hamiltonian to weight the probability measure on the space of graphs, assigning higher mass to graphs with “desirable” properties. In particular our analysis will be focused on the edge-triangle model, a two-parameter family of exponential random graphs where the Hamiltonian only includes edge and triangle densities. We borrow tools from statistical mechanics together with large deviations techniques to obtain limit theorems for the edge density in the so-called replica symmetric regime, where the limiting free energy of the model is known together with a complete characterization of the phase diagram. First, we determine the asymptotic distribution of the edge density, as the graph size n tends to infinity, in the entire replica symmetric regime. We then study the fluctuations of the edge density around its average for all parameter values outside the critical curve and off the critical point and we formulate conjectures about the behavior at criticality based on the analysis of a mean-field approximation of the model. Some of our results can be extended with no substantial changes to more general classes of exponential random graphs. Joint work with Alessandra Bianchi and Francesca Collet. The seminar will be on Zoom. You can find the information to join below.

Second call: „Junior female researchers in probability“ Dear colleagues, we would like to draw your attention to the third conference for "Junior female researchers in probability”, 4-6 October 2021 (postponed from last year due to the pandemic). The aim of this workshop is to promote young female researchers by giving them an opportunity to present their own work, and hear distinguished mathematicians who can inspire them to pursue a fulfilling career in probability. Keynote speakers: Nina Gantert (TU München) Eva Löcherbach (Paris) Invited speakers: Sigrid Källblad (Stockholm) Annika Lang (Göteborg) Elena Pulvirenti (Delft) Maite Wilke Berenguer (Berlin) The workshop will take place online and, if possible, as a hybrid event in Berlin. We warmly invite those who identify as female to submit abstracts for contributed talks, and apply for financial support for traveling to Berlin in case we can have a hybrid event. However, please be aware that being unable to travel should not restrain from submitting an abstract. There are special travel grants for female master students interested in gaining some insight into research and get in touch with researchers.. Of course everybody is very welcome to participate, but presentations and financial support are reserved for female participants. Deadline for submission of abstracts and funding requests: June 30, 2021. Please pass this information on to interested master students, PhD students and postdocs as well as your colleagues!

LTI@Unito webinar Lorenzo Schoenleber (CCA): “Investor Behavior under Prospect Theory: Evidence from Mutual Funds” | June 14, 2021 @12:45

Dear Colleagues, I am happy to share with you the following invitation to the Quantative Finance webinar organized by LTI@UniTO and Collegio Carlo Alberto, “Investor Behavior under Prospect Theory: Evidence from Mutual Funds” by Lorenzo Schoenleber (CCA), which will take place on Zoom on June 14th, at 12.45. Below you find the Zoom link and an abstract of the presentation. Best regards, Luca Regis <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/CkeqzI9VH3wAjL0mIewldcmVdn9Kyki4A1…> <#> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the following webinar <#> *June 14, 2021 | 12:45 - 13:45* *“Investor Behavior under Prospect Theory: Evidence from Mutual Funds”* *Lorenzo Schoenleber (Collegio Carlo Alberto)* <#> *Abstract. *This paper studies the investment behavior of investors and fund managers within the mutual funds industry. We find that investors are biased in their mutual fund purchase decisions in a way described by prospect theory: The prospect theory value predicts future mutual fund flows, despite the fact that it is not related to the mutual funds’ future performance. We show that the mutual funds’ prospect theory value contains incremental information compared to historical performance measures already discovered in the mutual fund flow literature, and subsumes the information content of variables related to the convexity in the flow-performance relationship. We find that mutual fund managers are not subject to any behavioral bias identifiable by prospect theory when selecting stocks for their mutual fund portfolio. The results are robust to various specifications. *Zoom Link:* *https://us02web.zoom.us/j/85611292343?pwd=U1dwYXZrZFQvR0RaZGwvZmplS2tFUT09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/79Qh76oDew-iI1lTKKd-JiGNLs42TkHRfm…>* Meeting ID: 856 1129 2343 Passcode: 401236 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/YmtAmHu7JhL3tEkSBLOh9PvpHnMR_PZzOe…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/AWpDX3iRxSwhx4MX6D5K64D_f2W6jUS_f2…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/4RHP7RFelHmPbN3l7D0GqNF1iSMpQHHnP4…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/EPbbUwncGLMOBC2qw2aNITsMvBTfaFVZcL…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/DcHnPK_RQAOSwsn5P0Ykl5hEaDyjahuL3n…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/EUM8gEcq3q4LvNepOA15xKXC8xWWbOaKbx…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/9VeN44_sxivBMcSIflgJy1DuZHDI0j6YLh…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.
