Simultaneous Approximation for an Exponential Operator Connected with x4/3

Abstract

Very recently, the authors in [5] proposed the exponential-type operator connected with and studied its convergence estimates. In the present research, we extend the study and obtain the general form of its 𝑝-th order moment; 𝑝 ∈ ℕ ∪ {0}. Further, we establish the simultaneous approximation for the operator under consideration.
