Approximation by a generalized Szász type operator for functions of two variables
Abstract
In the present paper, using a method given by
Jakimovski-Leviatan we define a new Sz\'{a}sz-Mirakjan type operator in
exponential weighted spaces for functions of two variables having
exponential growth at infinity. This operator is a generalization of two
variables of an operator defined by A. Ciupa. In this
study, we investigate approximation properties and also estimate the rate of
convergence for this new operator.
