FREE BOUNDARY REGULARITY IN THE ONE-PHASE STEFAN PROBLEM. PART II

In this seminar, a recent perturbative approach for the study of the free boundary regularity in the one-phase Stefan problem is presented. More precisely, we exhibit the fundamental steps of the method, whose main tool is an improvement of flatness property, in the spirit of the elliptic counterpart developed by D. De Silva. In this second part we will describe some technical results.
