Bézier-Bernstein-Schurer type operators
General Mathematics, 2022 Abstract We define Bézier variant of the κ- Bernstein-Schurer operators and study its various approximation properties. We present a direct theorem with the help of the Ditzian-Totik modulus of continuity. The rate of approximation for absolutely functions having a derivative equivalent to a bounded variation is also obtained.

Schurer operators of King type [PDF]
Creative Mathematics and Informatics, 2013 A class of linear and positive operators defined by finite sum which generalizes the classical Schurer’s operators in the King sense is constructed. For the mentioned class of operators, uniform convergences results, error estimations in terms of modulus of continuity and Voronovskaja type theorems are established.

Approximation by α-Bernstein-Schurer operator
Hacettepe Journal of Mathematics and Statistics, 2021 Summary: In this paper, we introduce a new family of generalized Bernstein-Schurer operators and investigate some approximation properties of these operators. We obtain a uniform approximation result using the well-known Korovkin theorem and give the degree of approximation via second modulus of smoothness.

On approximation properties of Baskakov–Schurer–Szász operators [PDF]
Applied Mathematics and Computation, 2016 In this paper, we are dealing with a new type of Baskakov-Schurer-Szasz operators (\ref{eq1}). Approximation properties of this operators are explored: the rate of convergence in terms of the usual moduli of smoothness is given, the convergence in certain weighted spaces is investigated.

King type modification of q-Bernstein-Schurer operators [PDF]
Czechoslovak Mathematical Journal, 2013 For a King-type modification of \(q\)-Bernstein-Schurer operators, some estimations of the rate of convergence are established. A Voronovskaja-type asymptotic formula is also obtained for these operators.

Kantorovich-Schurer bivariate operators [PDF]
Miskolc Mathematical Notes, 2004 Summary: Let \(p,q\) be two non-negative given integers. The sequence \((\tilde{K}_{m,n,p,q})_{m,n\in N}\), \(\tilde{K}_{m,n,p,q}:L_1([0,1]\times [0,1])\to C([0,1]\times[0,1])\), \[ \left(\tilde{K}_{m,n,p,q} f\right)(x,y) \] \[ = (m+p+1)(n+p+1)\times \sum\nolimits^{m+p}_{k=0}\sum\nolimits^{n+q}_{j=0} \tilde{p}_{m,k}(x)\tilde{p}_{n j}(y)\int\nolimits ...
