We also study the rate of statistical K-a(2)-convergence by using the weighted modulus of continuity and afterwards we present a non-trivial application.eninfo:eu-repo/semantics/openAccessDouble sequencesK-a-convergenceKorovkin theoremstatistical convergencealmost convergenceweighted spacesArticle631213910.33044/revuma.20102-s2.0-85125871745Q4WOS:000869186100002Q3
