Best trigonometric approximation and modulus of smoothness of functions in weighted grand Lebesgue spaces [PDF]

Қарағанды университетінің хабаршысы. Математика сериясы, 2019
In this work, first of all, Lpw),Ө (T) weighted grand Lebesgue spaces and Muckenhoupt weights is defined. The information about properties of these spaces is given. Let Tn be the trigonometric polynomial of best approximation.

Convergence of \(\lambda\)-Bernstein - Kantorovich operators in the \(L_p\)- norm

Journal of Numerical Analysis and Approximation Theory
We show the convergence of \(\lambda\)-Bernstein - Kantorovich operators defined by Acu et al. [J. Ineq. Appl. 2018], for functions in \(L_p[0,1],\, p\geq 1\). We also determine the convergence rate via integral modulus of smoothness.

Convergence analysis of semi-exponential Post-Widder operators

Miskolc Mathematical Notes
In the present article, we provide a recurrence relation for the semi-exponential Post-Widder operators (1.1) and estimate the moments for these operators.
