Pointwise Multipliers for Besov Spaces $B_{p,\infty }^{0,b}({\mathbb{R}}^n)$ with Only Logarithmic Smoothness

Ziwei Li, Winfried Sickel, Dachun Yang +1

In this article, we establish a characterization of the set $M(B_{p,\infty }^{0,b}({\mathbb{R}}^n))$ of all pointwise multipliers of Besov spaces $B_{p,\infty }^{0,b}({\mathbb{R}}^n)$ wi…
