Abstract

In this article, we develop bivariate extension of the operators introduced by Sehrawat and Kajla \cite{db3}. The convergence behaviour of the proposed operators is analyzed using various moduli of continuity, and Voronovskaja-type asymptotic theorems. The approximation behaviour is further investigated in Lipschitz-type spaces. In addition, the rate of convergence of the operators is illustrated through graphical representations, which are generated using the Maple computational software.
