13 Oct '25

Gentili colleghi, inoltro un annuncio sul prossimo meeting Dynstoch di statistica matematica e simulazione di processi stocastici, che si terra' a Göteborg in Svezia. (Dynstoch e' una conferenza che vanta piu' di venti edizioni. Una breve storia la trovate qui <https://sites.google.com/view/dynstoch>). Saluti, Umberto Picchini ************************** Dear colleagues, We are pleased to announce that the 2026 Dynstoch meeting will take place in Gothenburg, Sweden, on June 15–17, 2026. The meeting will be hosted by the Department of Mathematical Sciences at Chalmers University of Technology and the University of Gothenburg, and organized within the Dynstoch network. The aim of the Dynstoch series is to advance statistical inference and simulation for stochastic processes by combining modern probability tools with computationally intensive methods. Registration and abstract submission are expected to open in January 2026. More information and updates are available on the conference website: _https://dynstoch2026.pages.dev <https://dynstoch2026.pages.dev>_. We look forward to welcoming you to Gothenburg next June.

SPASS Seminar: Shuaijie Jiao - TUE 14.10 at 14:00
by francesco.triggiano＠sns.it 11 Oct '25

11 Oct '25

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: *Restoration of uniqueness by transport noise for stochastic 2D Boussinesq equations* by Shuaijie Jiao (University of Chinese Academy of Sciences, Beijing) The seminar will take place in person on *TUE, 14.10.2025 at 14:00* in Aula Seminari, Department of Mathematics, University of Pisa and streamed online here: Zoom Meeting https://us06web.zoom.us/j/82898233779?pwd=UwaJHrvAnbmj8TuuebRdW4DbqJy1zT.1 Meeting ID: 828 9823 3779 Passcode: 896251 Join instructions https://us06web.zoom.us/meetings/82898233779/invitations?signature=Ma1Od8oq… The organizers, G. Bet, F. Butori, A. Caraceni, F. Grotto, F. Triggiano, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: * *We investigate the inviscid 2D Boussinesq equations driven by rough transport noise of Kraichnan type with regularity index $\alpha\in (0,1/2)$. For all $1<p<\infty$, we establish the existence and uniqueness of probabilistic strong solutions for all $L^p$ initial vorticity and $L^2$ initial temperature, under the parameter constraint $0<\alpha< 1-1/(p\wedge 2)$. Based on the noise-induced anomalous regularity established by Coghi and Maurelli, we show that the stochastic Boussinesq system is stable with respect to the initial data, which not only implies the pathwise uniqueness but also enables us to directly prove the existence of probabilistically strong solutions without resorting to the compactness method. * *The talk is based on joint work with Dejun Luo.*

Christian Franq seminar, Ca' Foscari University, 13 October
by Roberto CASARIN 09 Oct '25

09 Oct '25

Dear Colleagues Professor *Christian Franq* (University of Lille - CREST-ENSAE) will give the seminar: *Penalized QMLE and model selection of time series regressions* *Monday, October 13, at 12:15 in Meeting Room 1* *Department of Economics, San Giobbe Campus* *Ca' Foscari University of Venice* It will also be possible to attend on Zoom here: https://unive.zoom.us/j/89661175677?pwd=mAtZP4LXqk5DwT5pNHkhJUemn7Sayq.1 All interested people are warmly invited to attend! rc Abstract: We examine a linear regression model applied to the components of a time series, aiming to identify time-varying, constant as well as zero conditional beta coefficients. To address the non-identifiability of parameters when a conditional beta is constant, we employ a lasso-type estimator. This penalized estimator simplifies the model by shrinking the estimates in favor of natural constant beta representations. Given that the model accommodates conditional heteroskedasticity and the relevant regressors are unknown, the total number of parameters to estimate can be quite large. To manage this complexity, we propose a multistep estimator that first captures the dynamics of the regressors before estimating the dynamics of the betas. This strategy breaks down a high-dimensional optimization problem into several lower-dimensional ones. Since we avoid making strict parametric assumptions about the innovation distributions, we use Quasi-Maximum Likelihood (QML) estimators. The non-Markovian nature of the global model means that standard convex optimization results cannot be applied. Nevertheless, we analyze the asymptotic distribution of the multistep lasso estimator and its adaptive version, deriving bounds on the maximum value of the penalty term. We also propose a nonlinear coordinate-wise descent algorithm, which is demonstrated to find stationary points of the objective function. The finite-sample properties of these estimators are further explored through a Monte Carlo simulation and illustrated with an application to financial data. Bio: Christian Francq is a distinguished econometrician and Professor of Statistics at the University of Lille, France. His research focuses on time series analysis, financial econometrics, and GARCH models, with a particular emphasis on theoretical and applied aspects of volatility modeling. He has made significant contributions to the development of nonlinear time series models, asymmetry in volatility, and inference for financial data. His research has been published in top-tier journals, and he continues to shape the field through both his academic work and collaborations.

CHANGE OF TIME AND LOCATION: De Finetti seminar: Walter Schachermayer, Oct. 13, 2025
by Alessandro Doldi 08 Oct '25

08 Oct '25

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 on October 13, 2025 at 15:30: Walter Schachermayer, University of Vienna NEW TIME AND LOCATION: Aula C04 Colombo-M (Entrance from Via Mangiagalli 25, Università degli Studi di Milano), h. 15:30 Title: Lacunary/Hereditary Limit Theorems in Probability and Analysis Abstract: J. Komlos proved in 1967 an extremely useful theorem. For any bounded sequence (f_n) in L^1 there is a subsequence n_k and a limiting function f such that f_{n_k} converges to f almost surely in Cesaro mean. The convergence not only holds for the subsequence f_{n_k}, but also for each of its sub-subsequences. This important result may be seen as an extension of the strong law of large numbers, pertaining to arbitrarily dependent sequences of random variables. We analyze also other lacunary/hereditary versions of classical variants of the law of large numbers. Special attention will be given to the law of large numbers of Hsu-Robbins-Erdös from 1947/49. We show that it is indispensable for the proof of a lacunary/hereditary version of this theorem to use approximations by exchangeable sequences of random variables (as opposed to martingale differences). This yields the first example verifying a conjecture by D. Aldous from 1977. Scientific Committee Prof. Simone Cerreia-Voglio (Univ.
