Approximation properties in abstract modular spaces for a class of general sampling-type operators

TL;DR: In this paper, the authors studied approximation properties for general integral operators of the form where G is a locally compact Hausdorff topological space, (Hw )w>0 is a net of closed subsets of G with suitable properties and, for every w>0, μ Hw is a regular measure on Hw.
Journal ArticleDOI

Abstract Korovkin-type theorems in modular spaces and applications

TL;DR: In this paper, the authors prove some versions of abstract Korovkin-type theorems in modular function spaces, with respect to filter convergence for linear positive operators, by considering several kinds of test functions.
Journal ArticleDOI

On Convergence Properties for a Class of Kantorovich Discrete Operators

TL;DR: In this paper, pointwise convergence theorems and asymptotic formulae of Voronovskaja type for a general class of Kantorovich discrete operators are given.

On Mellin convolution operators: a direct approach to the asymptotic formulae

TL;DR: In this paper, a quantitative Voronovskaja approximation for a general class of Mellin convolution operators is given. But this is not a direct approach to the study of pointwise approximation of such operators, without using the Fourier analysis.
