We present an example that satisfies our theorem but not satisfies the classical one and also, we study an extension to non-positive operators.eninfo:eu-repo/semantics/openAccessPower series methoddouble sequenceabstract Korovkin theoremArticle1341023103410.7153/oam-2019-13-712-s2.0-85078045677Q3WOS:000503449800008Q3
