| Abstract: | Exact inequalities of Jackson-Stechkin type have been obtained for the average moduli of continuity of mth order (m ?? ?) with the weight function. The exact values of any n-widths were calculated for the function classes, which are defined by the majorant and the indicated average magnitudes. |
