Moment computation in shift invariant spaces
International Journal of Stochastic Analysis, Volume 11, Issue 4, Page 465-479, 1998., 1997 An algorithm is given for the computation of moments of f ∈ S, where S is either a principal h‐shift invariant space or S is a finitely generated h‐shift invariant space. An error estimate for the rate of convergence of our scheme is also presented. In so doing, we obtain a result for computing inner products in these spaces.

Integral Modification of Lupaş‐Type Operators for Improved Approximation and Reduced Bias
Journal of Function Spaces, Volume 2026, Issue 1, 2026.In this paper, we introduce a generalized class of Lupaş‐type operators constructed through an integral modification of the classical formulation. Instead of using discrete point evaluations, the proposed operators are defined by means of weighted local integral averages together with a parameter‐dependent structure.

On approximation of functions and their derivatives by quasi‐Hermite interpolation
International Journal of Mathematics and Mathematical Sciences, Volume 19, Issue 2, Page 279-286, 1996., 1994 In this paper, we consider the simultaneous approximation of the derivatives of the functions by the corresponding derivatives of quasi‐Hermite interpolation based on the zeros of (1 − x2)pn(x) (where pn(x)is a Legendre polynomial). The corresponding approximation degrees are given. It is shown that this matrix of nodes is almost optimal.

The combined Shepard operator of inverse quadratic and inverse multiquadric type [PDF]
, 2022 Starting with the classical, the modified and the iterative Shepard methods, we construct some new Shepard type operators, using the inverse qua- dratic and the inverse multiquadric radial basis functions.

Journal of Mathematics, Volume 2026, Issue 1, 2026.This study introduces a novel family of hybrid Kantorovich‐type operators for the Baskakov–Schurer–Stancu class, integrated with a shape parameter α ∈ [0, 1]. We establish fundamental estimates and evaluate both the rate of convergence and the order of approximation utilizing the Korovkin theorem and the modulus of smoothness.
