APRG Seminar

Title: Optimal exponential integrability of maps with finite non convex energy
Speaker: Arka Mallick (Technion, Haifa, Israel)
Date: 24 February 2021
Time: 4 pm
Venue: Microsoft Teams (online)

In this talk, I would like to present some recent results regarding the behaviour of functions which are uniformly bounded under the action of a certain class of non-convex non-local functionals related to the degree of a map. In the literature, this class of functionals happens to be a very good substitute of the $L^p$ norm of the gradient of a Sobolev function. As a consequence various improvements of the classical Poincaré’s inequality, Sobolev’s inequality and Rellich-Kondrachov’s compactness criterion were established. This talk will be focused on addressing the gap between a certain exponential integrability and the boundedness for functions which are finite under the action of these class of non-convex functionals.
