Direct and Inverse Theorems for Beta-Durrmeyer Operators

Convergence estimates of certain gamma type operators

“…In the past few decades, integral operators have become an extensive area of research, and studies have been dedicated towards analyzing their approximation behaviors. We suggest previous articles 11–16 …”

“…We suggest previous articles. [11][12][13][14][15][16] King 17 proposed a modification of Bernstein operators which preserve the test functions e 0 (t) = 1 and e 2 (t) = t 2 . Inspired by this approach, many other mathematicians devoted their research to produce modifications of well-known approximation processes fixing certain (polynomial, exponential, or more general) functions and to study their approximation and shape preserving properties.…”
