Abelian varieties, modular forms and moduli

The aim of the meeting is to discuss recent developments, techniques and open questions in the area of abelian varieties and their moduli spaces, modular forms, number theory and combinatorics, automo...

On the (hidden) integrability structure of the deformed rule-54 reversible cellular automaton

I will discuss the integrability property of a stochastic and quantum deformation of the Rule 54 cellular automaton: the simplest microscopic (deterministic) reversible model in 1+1 discrete space and...

Sharp macroscopic blow-up behavior for the parabolic-elliptic Keller-Segel system in dimensions n ≥3

We study the space-time concentration asymptotics of radially decreasing solutions of the parabolic-elliptic Keller-Segel system of chemotaxis, in a ball or in the whole space. We show that, in dimens...

Multi-Agent Derivative-Free Optimization via Consensus Dynamics

This seminar presents a general overview of multi-agent, derivative-free metaheuristic methods for global nonconvex optimization, with a focus on stochastic interacting particle systems. We briefly re...

Studiare in Palestina Oggi

Conferenza sulla situazione della Scuola e dell'Università palestinese nel drammatico contesto attuale. L'iniziativa si svolge nell'ambito del progetto NoKalak in collaborazione tra Sapienza Universi...

On log Calabi-Yau manifolds

I will report on joint work with Tristan Collins where we look at pairs (X,D) where X is a complex projective manifold and D is a divisor with simple normal crossings such that K_X+D is trivial. I wil...

Strutture algebriche e omotopia

Nel mondo della topologia la relazione di uguaglianza è spesso sostituita da relazioni più deboli. Un esempio è l'equivalenza omotopica, che permette di sviluppare una teoria notevole. Nel seminario c...

K-stability of weighted hypersurfaces

In this talk I will discuss K-stability of weighted Fano hypersurfaces of dimension $n\geq 3$. The $3$-fold case has been established by [Kim-Okada-Won], [Sano-Tasin], [Campo-Okada]. In a joint work w...

Deterministic Particles and Smoothing Effects

Deterministic particle approximations are one of the possible ways to construct solutions to scalar conservation laws, to nonlinear diffusion equations, and to some Wasserstein gradient flows. Despite...

Recent Progress in Long-Time Dynamics in Kinetic Theory

Recently, there have been substantial advancements in our understanding of the long-time dynamics of plasmas, in particular the Vlasov-Poisson and Vlasov-Maxwell systems, as well as other related syst...

A counterexample to the log canonical Beauville–Bogomolov decomposition

In recent years, the work of Druel, Guenancia, Greb, Kebekus, Höring, and Peternell has shown that an analogue of the Beauville–Bogomolov (BB) decomposition holds for K-trivial varieties with klt sing...

Moduli spaces of semiorthogonal decompositions

The bounded derived category of coherent sheaves on a smooth projective variety $X$ is a sensible and somewhat subtle invariant of $X$. Its study is tightly related to rationality problems, MMP, Mirro...
