摘要 在两个基本算子假设下,以Richardson为光滑迭代,通过对算子在能量范数下作巧妙地估计,证明了以Richardson迭代为光滑化在无椭圆正则性假设前提下的非对称不定椭圆边值问题的多重网格方法是收敛的. In this paper, the operator is evaluated with energy norm for the non-symmetric and indefinite elliptic problem without regularity assumption, then the convergence of muhigrid algorithm is proved based on the Richardson iteration and two base assumptions.
