ERRATUM

In my article (A. P. Dzhabrailov, “On direct and inverse embedding theorems for weighted spaces”), published in Doklady Akademii Nauk, vol. 164, no. 1, 1965, the following corrections must be made.

In the construction of the functional spaces the number \(s \leq n\) appears; one must take only \(s = n\); consequently, in Theorems 1–7 it should be \(n_i = 1\) \((i = 1, \ldots, s = n)\). On p. 24, lines 6 and 4 from the bottom, \(B\) is printed; it should be \(W\).
