We also present an example that satisfies our theorem. Finally, we calculate the rate of convergence.eninfo:eu-repo/semantics/closedAccessPower series methodsThe double sequencesKorovkin-type theoremA Korovkin-type theorem for double sequences of positive linear operators via power series methodArticle22120921810.1007/s11117-017-0508-72-s2.0-85021082996Q2WOS:000425301900015Q2
