Some fixed point results regarding convex contractions of Presić type
AbstractIn the present paper, we introduce new types of Presić operators. These operators generalize the well-known Istrăţescu mappings, known as…
Addendum to the paper “an iterative method for a functional-differential equation of second order with mixed type argument“
AbstractAuthors Diana Otrocol, Tiberiu Popoviciu Institute of Numerical Analysis of Romanian Academy, Cluj-Napoca, Romania Veronica Ilea, Department of Applied Mathematics,…
Analytic vs. numerical solutions to a Sturm-Liouville transmission eigenproblem
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
Abstract In this paper we introduce a class of positive linear operators by using the “umbral calculus”, and we study…
On an approximation operator and its Lipschitz constant
AbstractIn this note we consider an approximation operator of Kantorovich type in which expression appears a basic sequence for a…
Compound operators constructed with binomial and Sheffer sequences
AbstractIn this note we consider a general compound approximation operator using binomial sequences and we give a representation for its…
On compound operators depending on s parameters
AbstractIn this note we introduce a compound operator depending on s parameters using binomial sequences. We compute the values of…
Natural convection from a vertical plate embedded in a non-Darcy bidisperse porous medium
Abstract This paper studies the steady, free convection boundary layer flow about a vertical, isothermal plate embedded in a non-Darcy…
Constraining Bose-Einstein condensate dark matter models with the galaxy rotation curves of the SPARC sample
AbstractIf dark matter did exist in the form of a self-interacting boson gas, when its temperature became lower than the…
