In this paper, we introduce and investigate a new class of the parametric generalization Baskakov-Schurer-Szász-Stancu operators, which considerably extends well-known classical approximation operators. For present Korovkin type theorem Grüss-Voronovskaya theorem, also study rate its convergence. Moreover, derive several results are related to operators in weighted spaces. Finally, prove some s...

The present paper deals with the study of the mixed summation integral type operators having Szász and Baskakov basis functions in summation and integration respectively. Here we obtain the rate of point wise convergence, a Voronovskaja type asymptotic formula, an error estimate in simultaneous approximation. We also study some local direct results in terms of modulus of smoothness and modulus ...

This paper concerns with a generalization of Sz?sz-Baskakov operators, which includes Boas-Buck-type polynomials. The convergence properties are studied in weighted space and the rate is obtained by using modulus continuity. A Voronovskaya-type theorem investigated. Also, theoretical results demonstrated choosing particular cases polynomials, namely Appell Hermite Gould-Hopper Laguerre polynomi...
