Geometry Graduate Colloquium

Title The Sard problem for the End-point map in step 2 Carnot groups
Speaker, Affiliation Luca Nalon,
Date, Time 21 September 2023, 15:00-16:00
Location HG G 19.1
Abstract The Sard theorem asserts that the set of critical values of a smooth map f:Rn→ Rmhas zero Lebesgue measure. The theorem has been disproved to various extents (see Bates 1993) when we replace the domain with an infinite-dimensional Banach space. The aim of the talk is to introduce the End-point map in the setting of step 2 Carnot groups and to prove an even stronger version of the Sard theorem for those kind of maps.

Title The Plateau problem and currents
Speaker, Affiliation Denis Marti,University of Fribourg, Switzerland
Date, Time 28 September 2023, 15:00-16:00
Location HG G 19.1
Abstract The Plateau problem asks for the existence of a minimal surface bounded by a given closed curve in Euclidean space. A surface is called minimal if it minimizes the area of all possible surfaces with the same boundary. In this talk we give an overview of the development from this classical version to higher dimensional analogues in Euclidean spaces and finally a generalized version in metric spaces. Along the way, we introduce currents, which were used to solve the problem, and discuss how this theory adapts to the different situations.
