Title Anosov Flows and the L-Space Conjecture
Speaker, Affiliation Misha Schmalian, University of Oxford
Date, Time 6 March 2025, 16:15-17:15
Location HG G 19.2
Abstract When studying dynamics on 3-manifolds a natural question is which 3-manifolds admit Anosov flows and if so how many such flows there are. This question remains open but substantial progress has been made in particular due to Anosov flows interacting well with one of the central questions in low-dimensional topology - the L-space conjecture. We will give an elementary introduction to the field and survey several recent results using these ideas.

Title Gradient Flows of Nonlocal Energies
Speaker, Affiliation Giacomo Cozzi, Università degli Studi di Padova
Date, Time 3 April 2025, 16:15-17:15
Location HG G 19.2
Abstract The aim of this talk is to present the theory of gradient flows on metric space. Given a functional defined on a Hilbert space, its gradient flow is the curve minimizing the functional in the fastest way possible, namely, following the opposite direction of its gradient. Starting from the pioneristic work of De Giorgi, it became possible to give a meaning to gradient flows even in spaces where the definition of gradient is not natural (i.e. on spaces which are not Hilbert). An important application is the case of gradient flows defined on the space of probability measures endowed with the Wasserstein distance. Using this theory, we will discuss two examples in which the functionals to be minimized are nonlocal (i.e., long range interaction) energies.
