Jumps in Besov spaces and fine properties of Besov and fractional Sobolev functions

Paz Hashash, Arkady Poliakovsky

In this paper we analyse functions in Besov spaces $B_{q,\infty }^{1/q}({\mathbb{R}}^N,{\mathbb{R}}^d),q\in (1,\infty )$, and functions in fractional Sobolev spaces $W^{r,q}(\mathbb{R}^N…
