Annuncio Seminario Sapienza // Martedì 10 Gennaio // Lorenzo Dello Schiavo
by Lorenzo Taggi 09 Jan '23

09 Jan '23

Martedì 10 Gennaio 2023, ore 14:00 Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker: *Lorenzo Dello Schiavo (ISTA, Vienna) *Titolo:* Scaling Limits of Random Walks, Harmonic Profiles, and Stationary Non-Equilibrium States in Lipschitz Domains *Abstract:* We consider the open symmetric exclusion (SEP) and inclusion (SIP) processes on a bounded Lipschitz domain Ω, with both fast and slow boundary. For the random walks on Ω dual to SEP/SIP we establish a functional-CLT-type convergence to the Brownian motion on Ω with either Neumann (slow boundary), Dirichlet (fast boundary), or Robin (at criticality) boundary conditions. We further show the discrete-to-continuum convergence of the corresponding harmonic profiles. As a consequence, we rigorously derive the hydrodynamic and hydrostatic limits for SEP/SIP on Ω, and analyze their stationary non-equilibrium fluctuations. Based on joint work arXiv:2112.14196 with Lorenzo Portinale (IAM Bonn) and Federico Sau (ISTA)

seminar on January 11, 2023 - Giulia Di Nunno - Reminder
by Emanuela Rosazza Gianin 07 Jan '23

07 Jan '23

Dear all, you are all invited to participate to the following seminar on *Wednesday 11th of January 2023 at 16:30* in Aula Seminari 4026 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 4th floor): Speaker: *Giulia Di Nunno* (University of Oslo) Titolo: *Sandwiched Volterra volatility models and hedging* Abstract: We present the Sandwiched Volterra Volatility (SVV) model and we discuss some of its characteristic properties. We then move to consider hedging and consider the explicit computation of quadratic hedging strategies. While the theoretical solution is well-known in terms of the non-anticipating derivative for all square integrable claims, the fact that these models are typically non-Markovian provides a concrete difficulty in the direct computation of conditional expectations at the core of the explicit hedging strategy. To overcome this difficulty, we propose a Markovian approximation of the model which stems from an adequate approximation of the kernel in the Volterra noise. We show some numerical simulations performed with different methods. Best wishes, Emanuela ****************************************** Emanuela Rosazza Gianin Department of Statistics and quantitative methods University of Milano-Bicocca Via Bicocca degli Arcimboldi, 8 20126 Milano - Italy Phone (0039) 02 64483208 e-mail: emanuela.rosazza1(a)unimib.it ******************************************

21st Informs APS, June 28-30 2023
by Sara Mazzonetto 06 Jan '23

06 Jan '23

Salve a tutti, Mi permetto d'inviare, a nome del comitato di organizzazione, l'annuncio di una conferenza in probabilità applicata che si terrà a fine giugno a Nancy. Cordiali saluti, Sara Mazzonetto %%%%%%%% Dear friends and colleagues, It is our great pleasure to announce that the 21st INFORMS Applied Probability Society conference will be held in Nancy, France, on June 28 - 30 2023. The Informs APS conference has been one of the most important international events in Applied Probability for over 4 decades. After having postponed the conference from back in 2021 due to Covid, we are all so excited to come together again as a community. The event will be an outstanding opportunity to hear (and give!) great talks and poster presentations at the cutting edge of research in Applied Probability. And the APS conference is an especially great opportunity for students and junior career scientists to meet many in the community, learn about new and interesting research directions, share their recent and ongoing work, establish new collaborations and friendships. Invited session chairs are currently in the process of inviting speakers, and there will also be many great sessions of contributed talks, as well as an excellent poster fair! Registration is now open, and all details may be found at : [ https://informs-aps2023.event.univ-lorraine.fr/ | https://informs-aps2023.event.univ-lorraine.fr/ ] The key dates are as follows: February 27th, 2023: deadline for student support applications. February 27th, 2023: submission deadline for titles and abstracts of invited sessions talks. March 6th, 2023: submission deadline for titles and abstracts of contributed talks. March 13th, 2023: submission deadline for posters. April 10th, 2023: notification of acceptance for student support grants. April 10th, 2023: notification of acceptance for contributed talks and posters. May 1st, 2023: deadline for early-bird registration. Hope to see you in Nancy this summer!

SPASS Seminar: Antonio Agresti - TUE 10.01 at 14:00
by Andrea Agazzi 04 Jan '23

04 Jan '23

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: *The primitive equations with transport noise* by Antonio Agresti (ISTA - Institute of Science and Technology Austria) The seminar will take place in person on *TUE, 10.01.2023 at 14:00 CET* in Aula Seminari, Department of Mathematics, University of Pisa and streamed online here <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Title: **The primitive equations with transport noise* *Abstract: **The primitive equations are one of the fundamental models for geophysical flows used to describe oceanic and atmospheric dynamics. In this talk I will discuss some recent results on the primitive equations with noise of transport type. In addition to transport noise, we also consider non-isothermal turbulent pressure. The dependence of the turbulent pressure on the temperature is a consequence of a stochastic Boussinesq approximation. For the primitive equations with transport noise and non-isothermal turbulent pressure, we provide a physical derivation and we discuss the global well-posedness for data in the critical spaces $H^1$. The latter result gives a non-trivial extension of the celebrated work by C. Cao and E.S. Titi on the deterministic model. Our approach is based on recent developments of maximal regularity techniques in the context of stochastic parabolic PDEs. If time allows, then I will also discuss further results in presence of rough noise.* *Based on joint works with M. Hieber (TU Darmstadt), A. Hussein (TU Kaiserslautern) and M. Saal (TU Darmstadt).*
