Embedding theorems for a class of functions. (Russian) Zbl 0638.41031
The author considers classes of Besov type of functions in mixed metric $$L_ p$$, $$p=(p_ 1,...,p_ n)$$ and obtains some imbedding theorems. In case $$p_ 1=p_ 2=...=p_ n$$ the obtained results coincide with known results of M. K. Potapov [Tr. Mat. Inst. Steklova 156, 143-156 (1980; Zbl 0454.46030)].
