Linear positive operators constructed by using Beta-type bases

6 years ago

AbstractStarting from a discrete linear approximation process that has the ability to turn polynomials into polynomials of the same degree,…

A stop over Jain operators and their generalizations

6 years ago

AbstractOn the last five decades the interest of the study of positive approximation processes have emerged with growing evidence. A…

Numerical benchmark study for flow in highly heterogeneous aquifers

6 years ago

AbstractThis article presents numerical investigations on accuracy and convergence properties of several numerical approaches for simulating steady state flows in…

On the convergence of the Newton-GMBACK method

7 years ago

AbstractWhen the GMBACK solver is used in the Newton iterates, the iterates may be written either as inexact Newton iterates…

Ergodic simulations of diffusion in random velocity fields

7 years ago

AbstractErgodic simulations aim at estimating ensemble average characteristics of diffusion in random fields from space averages. The traditional approach, based…

Common fixed points for Presic operators via simulation functions

7 years ago

AbstractIn this paper, using the concept of simulation function we present existence and uniqueness results for coincidence and common fixed…

Some fixed point results regarding convex contractions of Presić type

7 years ago

AbstractIn the present paper, we introduce new types of Presić operators. These operators generalize the well-known Istrăţescu mappings, known as…

AbstractAuthors Diana Otrocol, Tiberiu Popoviciu Institute of Numerical Analysis of Romanian Academy, Cluj-Napoca, Romania Diana Otrocol Veronica Ilea, Department of…

Analytic vs. numerical solutions to a Sturm-Liouville transmission eigenproblem

7 years ago

AbstractAn elliptic one-dimensional second order boundary value problem involving discontinuous coefficients, with or without transmission conditions, is considered. For the…

Approximation operators constructed by means of Sheffer sequences

7 years ago

Abstract In this paper we introduce a class of positive linear operators by using the “umbral calculus”, and we study…
