Free boundary regularity for the Stefan problem with fully nonlinear diffusion

Seminari di Analisi Matematica dell'Università e del Politecnico di Torino
Date: Wednesday, 29 March 2023 14:30 - 15:30

Venue: Alessandro Audrito - Aula Buzano (DISMA Politecnico di Torino)

In this talk I will present some recent results concerning the free boundary regularity in the Stefan problem with fully nonlinear diffusion. We show that the free boundary splits into a regular and a singular part: near regular points the free boundary is smooth in space and time, while the set of singular points is locally covered by a Lipschitz manifold of dimension n-1. This is a joint work with T. Kukuljian.
