Abstract:
In this paper we study the short time behavior of heat semigroup in connection wihe geometry of sets with finite perimeter; we assume $C^{1,1}$ regularity and we relate theat semigroup with curvatures of the initial datum. We also study the behavior wheingularities occur; this is the case when the mean curvature is no more a function, but ho be considered as a Radon measure.
