摘要
设Ω为IR^2平面上的有界区域,其边界(?)Ω适当光滑,考虑四阶调和方程: △~2表示双调和算子,f∈L^2(Ω).(1.1)式的物理模型为简支板的平衡方程,问题解的存在唯一性在[5]中已有证明.
In this paper the Schwarz alternating method for continuous and discrete simple plate problems are considered. The geometric convergence is obtained and a preconditional matrix of the finite element coefficient matrix is shown.
