Quantitative Global Estimates for Generalized Double Szasz-Mirakjan Operators

Abstract

We introduce the generalized double Szász-Mirakjan operators in this paper. We obtain several quantitative estimates for these operators. These estimates help us to determine some function classes $𝒮$ (including some Lipschitz-type spaces) which provide uniform convergence on the whole domain $[0,\infty )\times [0,\infty )$.
