Some approximation properties of new ( p , q ) $( p,q ) $ -analogue of Balázs–Szabados operators
Abstract In this paper, a new ( p , q ) $( p,q ) $ -analogue of the Balázs–Szabados operators is defined. Moments up to the fourth order are calculated, and second order and fourth order central moments are estimated. Local approximation properties of the operators are examined and a Voronovskaja ty...
