Abstract: In this paper, we give the strong converse inequalities of type B with the new K-functional Kλα(f,t2)w(0 ≤λ≤ 1, 0 < α < 2) on weighted approximation for Szász-Mirakjan operators, which extend the previous results.


Key words: Száz-Mirakjan operators, strong converse inequalities, approximation
