# Estimates for bilinear approximations of the classes TeX of periodic functions of two variables

Solich K. V.

Abstract

We obtain exact-order estimates for the best bilinear approximations of the classes $S_{p, \theta}^{\Omega} B$ of periodic functions of two variables in the space $L_q$ for some relations between the parameters $p, q, \theta$.
