Abstract: In a space of periodic functions with mean-square norm, we find the values of widths for some functional classes given by means of a modulus of continuity generated by an arbitrary difference operator and a weight function.

Keywords: Jackson inequality; generalized modulus of continuity; widths of functional classes.
