The convergence of the corresponding sequences is discussed in exponential weighted spaces, and a Voronovskaya type result is given. Also we define a new weighted modulus of smoothness and determine the approximation order of the constructed operators. Finally, we study the goodness of the estimates of our new operators via saturation results.eninfo:eu-repo/semantics/closedAccessSzasz-Mirakyan operatorsbetter estimateweighted approximationpointwise convergenceArticle7231393140410.1007/s00025-017-0665-92-s2.0-85014265948Q2WOS:000414940700024Q2
