J. KSIAM Vol.8, No.2, 23-38, 2004 SUPERCONVERGENCE OF FINITE ELEMENT METHODS FOR LINEAR QUASI-PARABOLIC INTEGRO-DIFFERENTIAL EQUATIONS

چکیده
We consider finite element methods applied to a class of quasi parabolic integro-differential equations in R. Global strong superconvergence, which only requires that partitions are quasi-uniform, is investigated for the error between the approximate solution and the Sobolev-Volterra projection of the exact solution. Two order superconvergence results are demonstrated in W (Ω) and Lp(Ω), for 2 ≤ p < ∞.

Linear quasi-parabolic integro-differential equations and their control appear in many scientific problems and engineering applications such as biology mechanics, nuclear reaction dynamics, heat conduction in materials with memory, and visco-elasticity, etc.. The existence and uniqueness of the solution of the linear quasi-parabolic integro-differential equations have been studied by Wheeler M....
متن کاملSemi-discrete Finite Element Approximations for Linear Parabolic Integro-di erential Equations with Integrable Kernels
In this paper we consider nite element methods for general parabolic integro-diierential equations with integrable kernels. A new approach is taken, which allows us to derive optimal L p (2 p 1) error estimates and superconvergence. The main advantage of our method is that the semidiscrete nite element approximations for linear equations, with both smooth and integrable kernels, can be treated ...

متن کاملSuperconvergence of a Finite Element Method for Linear Integro-differential Problems
We introduce a new way of approximating initial condition to the semidiscrete finite element method for integro-differential equations using any degree of elements. We obtain several superconvergence results for the error between the approximate solution and the Ritz-Volterra projection of the exact solution. For k > 1, we obtain first order gain in Lp(2≤ p ≤∞) norm, second order in W1,p(2≤ p ≤...
