Characteristic Functions for Sturm-Liouville Problems with Nonlocal Boundary Conditions
Journal Title: Mathematical Modelling and Analysis - Year 2009, Vol 14, Issue 2
Abstract
This paper presents some new results on a spectrum in a complex plane for the second order stationary differential equation with one Bitsadze--Samarskii type nonlocal boundary condition. In this paper, we survey the characteristic function method for investigation of the spectrum of this problem. Some new results on characteristic functions are proved. Many results of this investigation are presented as graphs of characteristic functions. A definition of constant eigenvalues and the characteristic function is introduced for the Sturm--Liouville problem with general nonlocal boundary conditions.

On Solutions of Neumann Boundary Value Problem for the Liénard Type Equation
We provide conditions on the functions [i]f(x) [/i]and [i]g(x)[/i], which ensure the existence of solutions to the Neumann boundary value problem for the equation [i]x''+f(x)[sup][/sup]x[sup]'2[/sup]+g(x)=0.[/i]

Numerical Study of the Rosensweig Instability in a Magnetic Fluid Subject to Diffusion of Magnetic Particles
The present study is devoted to the classical problem on stability of a magnetic fluid layer under the influence of gravity and a uniform magnetic field. A periodical peak-shaped stable structure is formed on the fluid s...
Finite Difference Scheme for a Singularly Perturbed Parabolic Equations in the Presence of Initial and Boundary Layers
The grid approximation of an initial-boundary value problem is considered for a singularly perturbed parabolic reaction-diffusion equation. The second-order spatial derivative and the temporal derivative in the different...
