Abstract:In this paper, we introduce a generalization of the Stancu-Schurer operators based on q-integers and get a Bohman-Korovkin type approximation theorem of these operators. We also compute the rate of convergence by using the first modulus of smoothness and give some numerical result of operators based on Matlab algorithms.

. In this paper, the Schurer-Stancu generalized Boolean sum (GBS, for short) approximation formula is considered and it’s remainder term is expressed in terms of bivariate divided differences. When the approximated function is sufficiently smooth, an upper bound estimation for the remainder term is also established. As particular cases, GBS Schurer and respectively GBS Bernstein approximation formulas are obtained and the expressions of their remainder are explicitly given.

“…Zeng in [23]. C.V. Muraru and A.M. Acu in [24] studied the Durrmeyer variant of the q-Bernstein-Schurer defined in [22] using uniform convergence. Our choice is to use both the uniform convergence and the statistical convergence to establish some approximation theorems for the Durrmeyer variant of the modified q-Bernstein-Schurer operators.…”

“…The goal of the present paper is to introduce a Kantorovich variant of q-Stancu operators and investigate their approximation properties. Many generalizations and applications of the Stancu operators were considered in the last years ( [1,2,11,15]).…”
The goal of this paper is to introduce new q-Stancu-Kantorovich operators and to study some of their approximation properties. A convergence theorem using the well known Bohman-Korovkin criterion is proven and the rate of convergence involving the modulus of continuity is established. Furthermore, a Voronovskaja type theorem is also proven.
