Title	Inverse Estimates for Lupas-Baskakov Operators
Authors	Ye, Peixin; Song, Zhanjie
Abstract	We establish Stechkin-Marchaud-type inequal-ities for some Feller operators by using some modified Ditzian-Totik modulus of smooth -ness. Then we derive some inverse results for this family of operators. Moreover combining the inverse results with the direct estimates we obtain a approximation equivalent theorem.
