论文摘要
在目前的贡献中,我们提出了所谓的虚拟空间引理的新证明。为了证明,我们在摩尔 - 纯伪伪二线逆上表现出明确的表达,这是与亚域分区分解相关的地图的倒数。
In the present contribution we propose a new proof of the so-called fictitious space lemma. For the proof, we exhibit an explicit expression for the inverse of additive Schwarz preconditioners in terms of Moore-Penrose pseudo inverse of the map associated to the decomposition over the subdomain partition.
