Abstract

In approximation theory, moments play an essential role. By the well known theorem of Korovkin, one can study the convergence of operators. Recently, in Gupta et al. (Modern discrete mathematics and analysis. Springer, 2017 [66]), the moments of some discrete and Kantorovich type operators were calculated by using the concept of moment generating functions. Also, Gupta et al. in (Gupta et al. in Recent advances in constructive approximation theory. Springer, Cham, 2018 [68]) estimated central moments of certain operators using this approach.
