Cari tutti, vi comunico che mercoledì (dopodomani) ore 17 in sala riunioni ci sarà il seminario di Danila Cherkashin (Bulgarian Academy of Sciences) dal titolo: "Steiner & Gilbert-Steiner Problems". Ovviamente siete tutti invitati a partecipare. E. (per chi aveva visto l'annuncio sul sito del dipartimento ho spostato l'orario dalle 15 alle 17 per via del consiglio di dipartimento).

Geometric Analysis seminar: NICOLA GIGLI, 22 ottobre
by Alessandra Pluda 19 Oct '25

19 Oct '25

Dear all, We are pleased to announce a SNS-UNIPI Geometric Analysis seminar. On Wednesday, October 22nd, 2025, at 2 pm in the Sala Conferenze at PUTEANO, we will have the pleasure of listening to NICOLA GIGLI (SISSA), who will hold a double seminar: the first hour will be more basic and accessible to everyone, and the second hour will be more specialized. Title: Trading linearity for ellipticity - a novel approach to global Lorentzian geometry Abstract: The concepts of Sobolev functions, elliptic operators and Banach spaces are central in modern geometric analysis. In the setting of Lorentzian geometry, however, unless one restricts the attention to Cauchy hypersurfaces these do not have a clear analogue, due to the signature of the metric tensor. Aim of the talk is to discuss some recent observations in this direction centered around the fact that for $p<1$ the $p$-D’Alambertian is elliptic on the space of time functions. The talk is mostly based on joint project with Beran, Braun, Calisti, McCann, Ohanyan, Rott, Saemann. In the second part of the talk I will dig down into the concept of `hyperbolic Banach space’, extracted from an upcoming work of mine. --------------------------------------------------------------------------------------------------------- Best, Alessandra

Care tutte, cari tutti, Con la presente si annuncia il seguente seminario di Analisi: GIOVEDì 09 OTTOBRE 2025, ore 16 in AULA RIUNIONI del Dipartimento, avremo il piacere di ascoltare ALICE MARVEGGIO (U. BONN), che terrà un seminario<https://www.dm.unipi.it/en/seminar/?id=68c02f248ecc6e0c5ede7ca8> dal titolo "The Verigin problem with phase transition as gradient flow". Trovate l'abstract qui sotto. A presto, Luigi ————————————————— Dear all, We announce the following Analysis seminar: on THURSDAY 09 OCTOBER 2025, 4pm in AULA RIUNIONI of the Dept. of Math., we will have the pleasure of listening to ALICE MARVEGGIO (U. BONN). The title of the talk<https://www.dm.unipi.it/en/seminar/?id=68c02f248ecc6e0c5ede7ca8> is "The Verigin problem with phase transition as gradient flow". Please find the abstract below. Best regards, Luigi Speaker: Alice Marveggio (Bonn) Title: The Verigin problem with phase transition as gradient flow Abstract: We study the modeling of a compressible two-phase flow in a porous medium. The governing PDE system is known as the Verigin problem with phase transition, which is the compressible analog to the Muskat problem. Our aim is to prove the convergence of an implicit time discretization scheme using the Wasserstein distance, obtaining distributional solutions in the limit that satisfy an optimal energy-dissipation rate. This talk is based on a joint work with Anna Kubin and Tim Laux.
