Abstract

In the Musielak-Orlicz type spaces SM{\mathcal S}_{\bf M}, exact Jackson-type inequalities are obtained in terms of best approximations of functions and the averaged values of their generalized moduli of smoothness. The values of Kolmogorov, Bernstein, linear, and projective widths in SM{\mathcal S}_{\bf M} are found for classes of periodic functions defined by certain conditions on the averaged values of the generalized moduli of smoothness.
