A surprising threshold for the validity of the method of singular projection
Given a compact manifold $ \mathcal{N} $ embedded into $ \mathbb{R}^ν $ and a projection $ P $ that retracts $ \mathbb{R}^ν $ except a singular set of codimension $ \ell $ onto $ \mathcal{N} $, we investigate the maximal range of parameters $ s $ and $ p $ such that the projection $ P $ can be used to turn an $ \mathbb{R}^ν $-valued $ W^{s,p} $ map into an $ \mathcal{N} $-valued $ W^{s,p} $ map. Devised by Hardt and Lin with roots in the work of Federer and Fleming, the method of projectio…

Heat content asymptotics for sets with positive reach
In this paper we study the heat content for sets with positive reach. In details, we investigate the asymptotic behavior of the heat content of bounded subsets of the Euclidean space with positive reach. The concept of positive reach was introduced by Federer in \cite{fed_1959} and widely developed in the following years (see for instance the recent book by Rataj and Zh{ä}le \cite{rat_zah_2019}). It extends the class of sets with smooth boundaries to include certain non-smooth and singular set…
