V. V. Zhuk

St. Petersburg State University, St. Petersburg, Russia

Abstract: We consider questions of strong approximation of continuous functions by positive operators. The estimations are established in the terms of modulus of continuity and its convex majorant.

Key words and phrases: strong approximation, modulus of continuity, positive operators, convex modulus of continuity.
