On Piecewise-Constant Approximation of Continuous Functions of n Variables in Integral Metrics

We consider the approximation by piecewise-constant functions for classes of functions of many variables defined by moduli of continuity of the form ω(δ1, ..., δ n ) = ω1(δ1) + ... + ω n (δ n ), where ω i (δ i ) are ordinary moduli of continuity that depend on one variable. In the case where ω i (δ...
