Approximation properties of a family of integral type operators

5 years ago

AbstractIn this paper we consider a general class of linear positive processes of integral type. These operators act on functions…

Global random walk solvers for fully coupled flow and transport in saturated/unsaturated porous media

5 years ago

AbstractIn this article, we present new random walk methods to solve flow and transport problems in saturated/unsaturated porous media, including coupled flow…

Accurate spectral collocation computations of high order eigenvalues for singular Schrödinger equations-revisited

5 years ago

AbstractIn this paper, we continue to solve as accurately as possible singular eigenvalues problems attached to the Schrödinger equation. We…

Accurate spectral collocation solutions to 2nd-order Sturm–Liouville problems

AbstractThis work is about the use of some classical spectral collocation methods as well as with the new software system…

Inequalities for Information Potentials and Entropies

6 years ago

AbstractWe consider a probability distribution \((p_0(x), p_1(x), . . .)\) depending on a real parameter \(x\). The associated information potential…

Accurate spectral collocation computation of high order eigenvalues for singular Schrödinger equations

6 years ago

AbstractWe are concerned with the study of some classical spectral collocation methods, mainly Chebyshev and sinc as well as with…

Accurate spectral collocation solutions to some Bratu’s type boundary value problems

6 years ago

AbstractWe solve by Chebyshev spectral collocation some genuinely nonlinear Liouville-Bratu-Gelfand type, 1D and a 2D boundary value problems. The problems…

On the Burton method of progressive contractions for Volterra integral equations

AbstractIn the paper [4] the author give a new method to study the existence and uniqueness of a solution on…

Spectral collocation based on quasi-classical orthogonal polynomials applied to solve a singular BVP from Hydrodynamics

6 years ago

AbstractIt is well established that spectral collocation methods based on classical orthogonal polynomials, in spite of their high order accuracy,…

Testing Bose-Einstein condensate dark matter models with the SPARC galactic rotation curves data

6 years ago
