Then, we discuss the results which are obtained by special choice of the scale function and the matrix sequences and we give an application that shows our results are stronger than studied before. Finally, we study an extension to non-positive linear operators.eninfo:eu-repo/semantics/closedAccessmodular spacesdouble sequencematrix summabilitystatistical convergenceabstract Korovkin theoremArticle131139156N/AWOS:000521758800012N/A
