Generalized weighted Stechkin–Marchaud-type inequalities for Baskakov–Durrmeyer operators

In this paper, we introduce new weighted modulus of smoothness ωφβ2(f;t)w,λ and prove the generalization of Stechkin–Marchaud-type inequalities of weighted approximation for Baskakov–Durrmeyer operators, from which the inverse results of Baskakov–Durrmeyer operators with ωφβ2(f;t)w,λ are obtained.
