An Analog of the Jackson Inequality for Coconvex Approximation of Periodic Functions

  • P. A. Popov

Abstract

We prove an analog of the Jackson inequality for a coconvex approximation of continuous periodic functions with the second modulus of continuity and a constant that depends on the location of the points at which a function changes its convexity.
