On the embedding of anisotropic Nikol’skiĭ-Besov mixed norm spaces

Abstract

The embedding of the anisotropic spaces $B_{p_1 , \ldots ,p_n ,\theta }^{\omega _1 , \ldots ,\omega _n } \left( {\mathbb{R}^n } \right)$ with mixed norm is studied. We establish some necessary and sufficient conditions of the embedding $B_{p_1 , \ldots ,p_n ,\theta }^{\omega _1 , \ldots ,\omega _n } \left( {\mathbb{R}^n } \right) \subset L^{q_1 , \ldots ,q_n } \left( {\mathbb{R}^n } \right)$.
