%0 Journal Article %T Approximation theorems for modified Szasz-Mirakjan operators in polynomial weight spaces %A Monika Herzog %J Le Matematiche %D 1999 %I University of Catania %X In this paper we will study properties of Szasz-Mirakjan type operators A_n^¦Í , B_n^ ¦Í defined by modified Bessel function I_¦Í . We shall present theorems giving a degree of approximation for these operators. %K Linear positive operators %K Degree of approximation %K Bessel function %U http://www.dmi.unict.it/ojs/index.php/lematematiche/article/view/315
