We also study the rates of convergence of positive linear operators with the help of the modulus of continuity.eninfo:eu-repo/semantics/openAccessmatrix summabilitypositive linear operatorsKorovkin theorymodulus of continuityrates of convergenceA-summation process and Korovkin-type approximation theorem for double sequences of positive linear operatorsArticle62228129210.2478/s12175-012-0009-x2-s2.0-84857777917Q2WOS:000300894700009Q2
