due seminari in SNS domani

Buongiorno a tutti, annuncio due seminari che si terranno in scuola domani. A presto, Alessandra Tuesday May 23, 10:00 Aula Volterra (Scuola Normale) Michael Cowling (University of New South Wales) Title: Hardy spaces in exotic geometries Abstract: The Heisenberg group appears in complex analysis as the boundary of a Siegel domain. Study of the boundary values of holomorphic functions leads to questions in analysis on the Heisenberg group, equipped with a flag geometry, in which the balls of classical geometry are replaced by the products of a ball in the sub-Riemannian geometry and an interval in the central variable. Flag Hardy spaces are a tool for solving problems in flag geometry; they present many features in common with Hardy spaces on product spaces. This talk focusses on the theory of flag Hardy spaces on the Heisenberg group, and on the difficulties which arise when one tries to extend to more exotic geometries. Alessio Martini (Politecnico di Torino) Title: A sharp multiplier theorem on solvable extensions of Heisenberg and related groups Abstract: Let L be a sub-Laplacian on a sub-Riemannian manifold M. It has been long known that, under fairly general assumptions on L and M, an operator of the form F(L) is L^p-bounded (1<p<infinity) whenever the spectral multiplier F satisfies a scale-invariant smoothness condition of sufficiently large order, related to the Hausdorff dimension and the volume growth of M. The problem of determining the minimal smoothness assumption, however, remains wide open in general. In recent years, a number of examples have been discovered where the minimal condition for L^p-boundedness turns out to be related to the topological dimension, which is smaller than the Hausdorff dimension when L is not elliptic. In joint work with Paweł Plewa (arXiv:2305.03467), we show that this surprising phenomenon also happens on manifolds with exponential volume growth.

Lo speaker sarà Luca Spolaor (UC San Diego). ————————————————————— Dear all, The next ERC VaReg seminar will be held on Thursday 18 May, at 17:00, in AULA MAGNA of the Department of Mathematics. ————————————————————— Speaker. Luca Spolaor (UC San Diego). Title. Interior regularity for stationary two-dimensional multivalued maps. Abstract. Q-valued maps minimizing a suitably defined Dirichlet energy were introduced by Almgren in his proof of the optimal regularity of area minimizing currents in any dimension and codimension. In this talk I will discuss the extension of Almgren's results to stationary Q-valued maps in dimension 2. This is joint work with Jonas Hirsch (Leipzig).
