  • Abstract

In the paper, the authors introduce the Orlicz space corresponding to the Young function and, by virtue of the equivalent theorem between the modified $K$-functional and modulus of smoothness, establish the direct, inverse, and equivalent theorems for the linear combinations of Jacobi weighted Baskakov–Durrmeyer operators in the Orlicz spaces.

  • Keywords

Direct theorem, inverse theorem, equivalent theorem, approximation, $K$-functional, Orlicz space, Jacobi weight, Baskakov–Durrmeyer operator.
