%0 Journal Article %T Approximation properties of certain modified Szasz-Mirakyan operators %A Lucyna Rempulska %A Zbigniew Walczak %J Le Matematiche %D 2000 %I University of Catania %X We introduce certain modified Szasz - Mirakyan operators in exponential weighted spaces of functions of one variable. We give theorems on the degree of approximation and the Voronovskaya type theorem. %U http://www.dmi.unict.it/ojs/index.php/lematematiche/article/view/263
