Abstract
In this paper we introduce a class of bivariate discrete operators not necessarily positive and we give a general asymptotic formula for pointwise convergence. Applications to bivariate generalized sampling series and to some Szasz-Mirak'jan type operators are given.File in questo prodotto:
