Approximation by bicomplex beta operators in compact BC-disks

摘要

The main object of this paper is to extend some known approximation results for the complex beta operators of the first kind attached to analytic functions in strips of compact disks. The extensions of these approximation properties, which are presented here, involve bicomplex beta operators in compact BC-disk. Several other related results are also considered.
