Lp‐inverse theorem for modified beta operators
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 20, Page 1295-1303, 2003., 2003 We obtain a converse theorem for the linear combinations of modified beta operators whose weight function is the Baskakov operators. To prove our inverse theorem, we use the technique of linear approximating method, namely, Steklov mean.

Rate of convergence on Baskakov‐Beta‐Bezier operators for bounded variation functions
International Journal of Mathematics and Mathematical Sciences, Volume 32, Issue 8, Page 471-479, 2002., 2002 We introduce a new sequence of linear positive operators Bn,α(f, x), which is the Bezier variant of the well‐known Baskakov Beta operators and estimate the rate of convergence of Bn,α(f, x) for functions of bounded variation. We also propose an open problem for the readers.

On the degree of approximation by Gauss Weierstrass integrals
International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 9, Page 645-649, 2000., 2000 We obtain the degree of approximation of functions belonging to class Lip(ψ(u, v); p), p > 1 using the Gauss Weierstrass integral of the double Fourier series of f(x, y).

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.

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.

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.
