Approximation properties by Bézier variant of the Baskakov–Schurer–Szász–Stancu operators

In this paper, we have construct a new version of the Bézier-type Baskakov–Schurer–Szász–Stancu operators. For this new class of operators, uniform convergence is shown in any compact subset or positive real line. We prove Korovkin-type theorem, Voronovskaya-type theorem, and Grüss–Voronovskaya-type theorem. Moreover, at the end, we express the behavior of the operators in the Lipschitz-type space using the modulus of continuity and smoothness.
