On some summability methods for a q-analogue of an integral type operator based on multivariate q-Lagrange polynomials

Abstract

The present paper considers a q-analogue of an operator defined by Erkuş-Duman et al. (Calcolo, 45(1) (2008), 53-67) involving q-Lagrange polynomials in several variables. The Korovkin type theorems in the settings of deferred weighted A-statistical convergence and the power series method are investigated.
