Monday 12 January 2026, from 2 pm in Room U9-09 (U9 Building - Viale dell'Innovazione 10, Milano), Giulio Colombo (University of Milano) e Filippo Sarti (University of Pisa) will give the following talks
Speaker: Giulio Colombo
Title: Nonnegative Ricci curvature and rigidity of prescribed mean curvature graphs
Abstract: In this talk I will discuss some rigidity and classification results for graphs of prescribed mean curvature on Riemannian manifolds of nonnegative Ricci curvature. In the first part of the talk I will focus on the case of entire minimal graphs on complete open manifolds, reviewing some Liouville and Bernstein type properties. Then, I will discuss the case of graphs of prescribed mean curvature on manifolds with boundary, obtaining some splitting results both for the graph and for the underlying manifold under suitable boundary conditions.
Speaker: Filippo Sarti
Title: Dynamical approaches to simplicial volume
Abstract: The power of dynamics in the study of geometric invariants as simplicial volume was already understood by Gromov. Over the years, many people developed different approaches to simplicial volume intertwining geometry, algebra and dynamics. In this talk, we will make a general overview about this philosophy, trying to understand the real advantages and the side effects that can arise. I will illustrate a recent new strategy involving foliations, describe connections with other (co)-homology theories and hint possible future applications.
