An overview of regularity results for the Laplacian and -Laplacian in metric spaces
Ivan Yuri Violo
We review some regularity results for the Laplacian and -Laplacian in metric measure spaces. The focus is mainly on interior Hölder, Lipschitz and second-regularity estimates an…

Fat triangles inscribed in arbitrary planar domains
Ivan Yuri Violo
In 1964 A. Bruckner observed that any bounded open set in the plane has an inscribed triangle, that is a triangle contained in the open set and with the vertices lying on the bound…

A remark on two notions of flatness for sets in the Euclidean space
Ivan Yuri Violo
In this note we compare two ways of measuring the -dimensional "flatness" of a set , where and . The first one is to consider the c…
