Abstract

We characterize compact embeddings of Besov spaces Bp,r0,b(ℝn) involving the zero classical smoothness and a slowly varying smoothness b into Lorentz-Karamata spaces \({L_{p,q;\overline b }}\)(Ω), where is a bounded domain in ℝn and \(\overline b \) is another slowly varying function.

Keywords
