The next session will be two weeks from now, on October 21sh, from 14:00 to 15:45 UTC. Bernard Derrida and Zhan Shi will talk about a simple toy-model for renormalization and disorder.

Please feel free to circulate this email, the information for getting on the mailing list can be found there https://www.owprobability.org/mailing-list. Probabilistically yours, Bastien Mallein and Sébastien Martinea --------- Renormalisation and disorder: a simple toy model (I) Bernard Derrida (Collège de France) LPSM is inviting you to a scheduled Zoom meeting. Topic: OWPS Seminar October 21st Bernard Derrida & Zhan Shi Time: Oct 21, 2021 03:45 PM Paris Renormalisation and disorder: a simple toy model (II) Zhan Shi (AMSS, Chinese Academy of Sciences) After a short review of our understanding of how a weak disorder or a low density of impurities affect the universality class of a phase transition, we will discuss a simple tree-like toy model for which one can prove that, due to disorder, the depinning transition becomes an infinite order transition of the Berezinski-Kosterlitz-Thouless type. This toy model was introduced to understand the depinning transition of a line from a random substrate, one of the simplest problems in the theory of disordered systems. This depinning transition has a long history among physicists and mathematicians. Still the nature of the transition, one of the central questions of the problem, remains unsolved. Joint work with Xinxing Chen, Victor Dagard, Yueyun Hu and Mikhail Lifshits.

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 15 Ottobre 2021, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Bas Kleijn *(University of Amsterdam) Title: *Confidence sets in a sparse stochastic block model with two * *communities of unknown sizes* Abstract: In a sparse stochastic block model with two communities of unequal sizes we derive two posterior concentration inequalities, that imply (1) posterior (almost-)exact recovery of the community structure under sparsity bounds comparable to well-known sharp bounds in the planted bi-section model; (2) a construction of confidence sets for the community assignment from credible sets, with finite graph sizes. The latter enables exact frequentist uncertain quantification with Bayesian credible sets at non-asymptotic graph sizes, where posteriors can be simulated well. There turns out to be no proportionality between credible and confidence levels: for given edge probabilities and a desired confidence level, there exists a critical graph size where the required credible level drops sharply from close to one to close to zero. At such graph sizes the frequentist decides to include not most of the posterior support for the construction of his confidence set, but only a small subset of community assignments containing the highest amounts of posterior probability (like the maximum-a-posteriori estimator). It is argued that for the proposed construction of confidence sets, a form of early stopping applies to MCMC sampling of the posterior, which would enable the computation of confidence sets at larger graph sizes.

Mini-course about Rough Volatility by Jim Gatheral CUNY
by Giacomo Bormetti 08 Oct '21

08 Oct '21

Dear all, in collaboration with Jim Gatheral from City University of New York we organize a mini-course about Rough Volatility. The course will take place only in presence in Bologna at the Department of Mathematics (Piazza di Porta San Donato 5). Below all the details. All interested people are kindly invited. Sincerely Giacomo Bormetti and Fabrizio Lillo Gio 14 Ottobre, 4:00-7:00 PM CET Aula Tonelli Jim Gatheral, Baruch College CUNY, New York Titolo: Rough volatility I Rough volatility connects the microstructure of financial markets with the large-scale behavior of volatility. This approach results in parsimonious models that are consistent across different time-scales and show remarkable agreement with econometric data. In this first lecture of two, we will focus on the econometric motivation of rough volatility and explore its consequences for pricing, focusing on the rough Bergomi model. As an application, we will show how to forecast realized variance and the forward variance curve. Gio 21 Ottobre, 4:00-7:00 PM CET Aula Tonelli Jim Gatheral, Baruch College CUNY, New York Titolo: Rough volatility II In this second lecture, we will present the microstructural foundation for rough volatility models. This leads to the class of affine forward variance (AFV models) and more recently to so-called super Heston models, a special case of which is the quadratic rough Heston model. We give a brief overview of recent developments, including numerical solution techniques. Numerical experiments are performed to give intuition for the effect of changing model parameters. Both lectures will be in the form of Jupyter notebooks that will be made available afterwards, including code to reproduce most of the computations.

Seminar by Francesca Biagini in Verona (Virtual)
by Alessandro Gnoatto 07 Oct '21

07 Oct '21

Prof. Francesca Biagini (LMU Munich) will give a virtual talk at our Department seminar. Date: 13 October 12:00 CEST. Title: "Reduced-form setting under model uncertainty with non-linear affine intensities" If you would like to attend via Zoom, please register at the following link, we will send you the details: https://docs.google.com/forms/d/e/1FAIpQLSe6_5W5PbKr9R3fufAahV1D4js4-6AAcEn… Abstract: In this talk we present a market model including financial assets and life insurance liabilities within a reduced-form framework under model uncertainty by following [1]. In particular we extend this framework to include mortality intensities following an affine process under parameter uncertainty, as defined in [2]. This allows both to introduce the definition of a longevity bond under model uncertainty in a consistent way with the classical case under one prior, as well as to compute it by explicit formulas or by numerical methods. We also study conditions to guarantee the existence of a càdlàg modification for the longevity bond’s value process. Furthermore, we show how the resulting market model extended with the longevity bond is arbitrage-free and study arbitrage-free pricing of contingent claims or life insurance liabilities in this setting. This talk is based on: [1] Francesca Biagini and Yinglin Zhang. Reduced-form framework under model uncertainty. The Annals of Applied Probability, 29(4):2481–2522, 2019.
