该文研究二维Maxwell方程组的混合有限元高精度近似.在均匀矩形网格上, 采用一阶Nedelec混合元空间, 有限元解经三次投影插值后, ......

证明了Hammerstein型非线性积分方程的配置解有渐近展开式y-y_n=h~(2m+2)W+O(h~(2m+2+r))其中W为[0,1]上与h无关的函数,r=min(2,2......

In this paper,we present the least-squares mixed finite element method and investigate superconvergence phenomena for th......
