Best approximation by analogues of “own” and “alien” hyperbolic crosses
The author studies the best approximation of classes of periodic functions of several real variables with a given majorant of the mixed moduli of continuity by analogues of “own” and “alien” hyperbolic crosses. The majorant has the power factors in different degrees and logarithmic factors in different degrees.
