Superconvergence Analysis of a New Lowest Order Nonconforming Mixed Finite Element Formulation

WANG Jian-bin;WU Zhi-qin;SHI Dong-yang;Basic Courses Department,Jiyuan Vocational and Technical College;School of Mathematics and Statistics,Xuchang University;School of Mathematics and Statistics,Zhengzhou University;  
A new lowest order triangular mixed finite element formulation for the quasilinear integro-differential equation of parabolic type is constructed.By utilizing the properties of the interpolation on the element and integration identity technique,the supercolose and superconvergence results for the corresponding varibles are obtained without Ritz-Volterra projection,which is one of indispensable tools in tradition finite element analysis.Thus the deficiencies in the previous liteature are overcome.
