Periodic boundary value problems of impulsive differential equations

Applicable Analysis, 1992
Periodic boundary value problems of impulsive differential equations with continuous or discontinuous right hand side will be studied by comparis-ing theorems and operator theory. Both existence and bounds of solutions will be obtained.

The solvability of a boundary-value periodic problem

Ukrainian Mathematical Journal, 1997
The authors study a periodic boundary value problem for the linear hyperbolic equation \[ \begin{aligned} u_{tt}-a^{2}u_{xx} &=g(x,t),(x,t)\in{\mathbb{R}}^{2},\tag{1}\\ u(0,t)&=u(\pi,t)=0,t\in{\mathbb{R}}, \tag{2}\\ u(x,t+T)&=u(x,t),(x,t)\in{\mathbb{R}}^{2}.

Rational-Fourier-series Approximations for Periodic Boundary-value Problems

IMA Journal of Applied Mathematics, 1984
The idea of using ratios of trigonometric polynomials to approximate periodic solutions of nonlinear ordinary differential equations is an interesting one. For this approach a Galerkin-type approximation scheme is used in the sense that the approximate differential equation is regarded as orthogonal to the basis functions.

Discontinuous Galerkin methods for periodic boundary value problems

Numerical Methods for Partial Differential Equations, 2006
AbstractThis article considers the extension of well‐known discontinuous Galerkin (DG) finite element formulations to elliptic problems with periodic boundary conditions. Such problems routinely appear in a number of applications, particularly in homogenization of composite materials.

Two point boundary value and periodic eigenvalue problems

Proceedings of the 1999 IEEE International Symposium on Computer Aided Control System Design (Cat. No.99TH8404), 2003
In this paper we link the discrete-time periodic eigenvalue problem with two point boundary value problems over the same interval. This gives a new formulation of periodic eigenvalue problems which also leads to a new and more economical scheme for computing periodic eigenvalues.
