二阶椭圆问题的稳定化杂交有限元分析

摘要

Stabilized hybrid finite element methods are developed for the second order elliptic problem. These methodologies are characterized by the following properties:[1] any stabilizing parameter is avoided. [2] the uniform ellipticity is obtained.[3] hybrid element pairs can be depicted as either nonconforming or can be expanded as conforming elements through the method used. [4] optimal error bounds are established.[5] the same arguments as this note may be easily applied to other three dimensional problems.
