    The paper deals with necessary and sufficient conditions for embeddings of Besov-Morrey spaces \(\mathcal{N}^s_{p,u,q} (\Omega)\) defined on bounded smooth domains. The authors are interested in three types of continuous embeddings:NEWLINENEWLINE\(\mathcal{N}^{s_1}_{p_1,u_1,q_1} (\Omega) \hookrightarrow \mathcal{N}^{s_2}_{p_2,u_2,q_2} (\Omega)\);NEWLINENEWLINE\(\mathcal{N}^{s_1}_{p_1,u_1,q_1} (\Omega) \hookrightarrow L_{p_2} (\Omega)\);NEWLINENEWLINE\(\mathcal{N}^{s_1}_{p_1,u_1,q_1} (\Omega) \hookrightarrow C(\Omega)\).NEWLINENEWLINEPartially, they have found necessary and sufficient conditions. In any case, the authors have found necessary and sufficient conditions for the compactness of those embeddings.
