In this paper, we construct a sequence of modified Stancu-Baskakov operators for a real valued function bounded on [Formula: see text], based on a function [Formula: see text]. This function [Formula: see text] is infinite times continuously differentiable on [Formula: see text] and satisfy the conditions [Formula: see text] and [Formula: see text] is bounded for all [Formula: see text]. We stu...

Abstract We consider the Post–Widder operators of semi-exponential type, which are a generalization exponential connected with $$x^2$$ x 2 . This modification has beauty to find difference other operators, while original do not have such property. estimate quantitative ...
