On the limiting behaviour of some nonlocal seminorms: a new phenomenon

Analysis of PDEs 2021-02-26 v2

Abstract

In this note we study the behaviour as s0+s\to 0^+ of some semigroup based Besov seminorms associated with a non-symmetric and hypoelliptic diffusion with a drift. Our results generalise a previous one of Maz'ya and Shaposhnikova for the classical fractional Sobolev spaces Ws,pW^{s,p}, and they also underscore a new phenomenon caused by the presence of the drift.
