A solution of 3D Helmholtz equation for boundary geometry modeled by Coons patches using the Parametric Integral Equation System

open access: yesArchives of Acoustics, 2014
In this paper, the authors propose an algorithm for numerical solution of the 3D Helmholtz equation using the Parametric Integral Equation System (PIES). The PIES, unlike the traditional Boundary Integral Equation (BIE), is characterized by the fact that

Duality in Noetherian Integral Domains

open access: yesRocky Mountain Journal of Mathematics, 1999
Let \(A\) be a torsion-free abelian group of rank one and let \(C(A)\) denote the class of torsion-free abelian groups \(M\) of finite rank such that \(M\) embeds as \(\text{End}(A)\)-submodule of \(A^n\) for some \(n\). Then the map \(M\) to \(\Hom(M,A)\) on \(C(A)\) defines a duality. This is called Warfield duality. In this paper, the author gives a

Existence and Ulam stabilities for Hadamard fractional integral equations with random effects

open access: yesElectronic Journal of Differential Equations, 2016
This article concerns the existence and Ulam stabilities for a class of random integral equations via Hadamard's fractional integral. Our main tools is a random fixed point theorem with stochastic domain.

United Boundary-Domain Integro-Differential and Integral Equations to the Mixed BVP for a Compressible Stokes System with Variable Viscosity

open access: yesJournal of Mathematics
The mixed BVP for a compressible Stokes system of PDEs with variable viscosity is considered in a bounded domain of three dimensions. Based on a specially constructed parametrix (Levi function), the problem is reduced to the united boundary-domain ...
