耦合有限元空间上Poisson方程的广义差分法

Generalized Difference Methods for Poisson's Equation on Coupling Finite Element Space

本文讨论了耦合有限元空间上Poisson方程的一种广义差分法 ,试探函数空间为耦合的有限元空间 ,检验函数空间为与对偶单元相对应的分片常数空间 ,并给出了误差估计 .

In this paper,a kind of generalized difference methods for Poisson's equation was given.The trial function space is coupling finite element space and the test function space is piecewise constant space about the dual elements,also the error estimate was given.
