On certain Baskakov-Durrmeyer type operators [PDF]

open access: yesSurveys in Mathematics and its Applications, 2010
This paper is a study of the degree of approximation by the linear combinations of the derivatives of certain Durrmeyer type integral modification of the Baskakov operators in terms of the higher order modulus of smoothness.

The approximation of bivariate Chlodowsky-Szász-Kantorovich-Charlier-type operators

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we introduce a bivariate Kantorovich variant of combination of Szász and Chlodowsky operators based on Charlier polynomials. Then, we study local approximation properties for these operators.

Approximation of signals (functions) belonging to certain Lipschitz classes by almost Riesz means of its Fourier series

open access: yesJournal of Inequalities and Applications, 2016
To start with, signals are dealt with as functions of one variable and images are shown by elements of two variables. The investigation of these ideas is directly related to the transpiring area of information technology.

Bi-Criteria Approximation Algorithms for Bounded-Degree Subset TSP [PDF]

open access: yes, 2022
We initiate the study of the Bounded-Degree Subset Traveling Salesman problem (BDSTSP) in which we are given a graph G = (V,E) with edge cost c_e ≥ 0 on each edge e, degree bounds b_v ≥ 0 on each vertex v ∈ V and a subset of terminals X ⊆ V.

Asymptotic behavior of solutions to difference equations in Banach spaces

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We investigate the asymptotic properties of solutions to higher order nonlinear difference equations in Banach spaces. We introduce a new technique based on a vector version of discrete L'Hospital's rule, remainder operator, and the regional topology on ...
