Abstract

Exact Jackson-type inequalities are obtained in terms of best approximations and averaged values of generalized moduli of smoothness in the spaces Sp{\mathcal S}^p. The values of Kolmogorov, Bernstein, linear, and projective widths in the spaces Sp{\mathcal S}^p are found for classes of periodic functions defined by certain conditions on the averaged values of the generalized moduli of smoothness.
