On gamma-type approximation operators

Approximation by modified q‐Gamma type operators in a polynomial weighted space

“…Krech 27 considered modified Gamma type operators defined on a certain weighted space and obtained the rate of convergence in terms of some Ditzian–Totik moduli of smoothness. Leviatan 28 proposed two types of Gamma‐operators defined by means of some convolution kernels and the Studden's kernels and showed the uniform convergence of these operators on compact intervals of $$$ \left(0,\infty \right) $$$. Özçelik et al 29 presented a modification of the Gamma operators and studied a Voronovskaya‐type theorem, rate of convergence, weighted approximation, and pointwise estimates.…”
