Also, we give a Korovkin-type approximation theorem using this new type of convergence. Finally we give some further developments.eninfo:eu-repo/semantics/closedAccessA-statistical convergencetriangular A-statistical convergencetriangular densityKorovkin theoremrate of convergenceArticle683-427129110.1007/s00025-015-0433-72-s2.0-84944171269Q2WOS:000362896800001Q1
