The numerical solution of the Dirichlet problem for the Helmholtz equation
(Pergamon-elsevier Science LtdOxfordInglaterra, 1996)
Utilizando o metódo das características para resolver uma equação diferencial parcial hiperbólica
(Universidade Tecnológica Federal do ParanáCampo MouraoPrograma de Pós-Graduação em Matemática, 2013)
Depth study of the Wave Equation where there was a concern with the deduction of the wave equation for longitudinal vibrations with a dimension, bringing his detailed demonstration by Newton’s Second Law, applying the ...
Numerical Solution for Fuzzy Partial Differential Equations with Interactive Fuzzy Boundary Conditions
(2022-01-01)
This paper presents a numerical method to solve fuzzy partial differential equations, where the initial and boundary conditions are given by interactive fuzzy numbers. Interactivity is a relationship between fuzzy numbers ...
A numerical scheme based on mean value solutions for the Helmholtz equation on triangular grids

Comparison Between Numerical Solutions of Fuzzy Partial Differential Equations via Interactive and Non-interactive Arithmetics: Application to the Heat Equation
(2022-01-01)
This paper provides a new numerical solution to partial differential equations, where the initial and boundary conditions are given by interactive fuzzy numbers. The interactivity considered here is the one obtained from ...
On the numerical solution of the one-dimensional Schrödinger equation
(IOP Publishing, 2016-04)
We discuss two sources of error in the numerical calculation of eigenvalues and eigenfunctions of the one-dimensional Schrödinger equation. By means of suitable examples we analyse the effect of both a finite mesh size and ...
On a transmission problem for dissipative Klein-Gordon-ShrÄodinger equations
(Campo Mourao, 2004)
In this paper we consider a transmission problem for the Cauchy problem of coupled dissipative Klein-Gordon-Shr¨odinger equations and we prove the existence of global solutions.
Computer simulation of the stochastic transport equation
(EMAp - Escola de Matemática Aplicada, 2015)
In this article the numerical approximation of the stochastic transport equation is considered. We propose a new computational scheme for the effective simulation of the solutions of this equation. Results on the convergence ...
Monotone positive solutions for a fourth order equation with nonlinear boundary conditions
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This work is concerned with the existence of monotone positive solutions for a class of beam equations with nonlinear boundary conditions. The results are obtained by using the monotone iteration method and they extend ...
