摘要
本文研究了电磁场中关于共振现象的一类退化的椭圆问题 ,提出了最小二乘混合有限元方法 .这一方法的好处是可以去掉传统混合元空间的LBB条件所得到的系数矩阵是对称正定的 ,使得法语解更加方便 .本文得到了最小二乘混合有限元方法的L2 和H1估计 .
We present the least-squares mixed finite element methods for the first-order system formulation corresponding to degener ate elliptic problem, which arising in the study of the electromagnetic field in a resonant structure with cylindrical symmetry. The main results are that L 2 and H 1 error estimates of least-squares mixed finite element methods are obtained.
