چکیده
In this paper we consider a reduced order method for the approximation of eigensolutions Laplace problem with Dirichlet boundary condition. We use time continuation technique that consists in introduction fictitious parameter. POD approach and present some theoretical results showing how to choose optimal dimension basis. The our computations, related first eigenvalue, confirm behavior approximate solution.

A Posteriori Error Estimates for the Finite Element Approximation of Eigenvalue Problems
This paper deals with a posteriori error estimators for the linear finite element approximation of second order elliptic eigenvalue problems in two or three dimensions. First, we give a simple proof of the equivalence, up to higher order terms, between the error and a residual type error estimator. Second, we prove that the volumetric part of the residual is dominated by a constant times the ed...
متن کاملOptimal order finite element approximation for a hyperbolic integro-differential equation
Semidiscrete finite element approximation of a hyperbolic type integro-differential equation is studied. The model problem is treated as the wave equation which is perturbed with a memory term. Stability estimates are obtained for a slightly more general problem. These, based on energy method, are used to prove optimal order a priori error estimates.
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Finite element approximation of fractional order elliptic boundary value problems
A finite element numerical method is investigated for fractional order elliptic boundary value problems with homogeneous Dirichlet type boundary conditions. It is pointed out that an appropriate stiffness matrix can be obtained by taking the prescribed fractional power of the stiffness matrix corresponding to the non-fractional elliptic operators. It is proved that this approach, which is also ...
