Then, we use this notion to prove a Korovkin type approximation theorem and present an application that satisfies our new main theorem but does not satisfy classical ones. Finally, we study the rate of convergence of positive linear operators.eninfo:eu-repo/semantics/closedAccess2 VariablesSummabilityOperatorsTheoremsArticle2162712-s2.0-85121240802N/AWOS:000635354500007N/A
