Abstract

Deo [5] introduced n-th Durrmeyer operators defined for functions integrable in some
interval I. There are gaps and mistakes in some of his lemmas and theorems. Further, in his paper [4] he did not give results on simultaneous approximation as the title reveals. The purpose of this paper is to correct those mistakes.

Keywords

Durrmeyer type operators; ordinary approximation; simultaneous approximation
