On the Approximation of Periodic Functions in L2 and the Values of the Widths of Certain Classes of Functions

The sharp Jackson–Stechkin inequalities are received, in which a special module of continuity Ωem(f;t) determined by Steklov’s function is used instead the usual modulus of continuity of mth order ωm(f;t). Such generalized modulus of continuity of mth order were introduced by V.A. Abilov and F.V. Ab...
