Abstract:In this paper, the first family of conforming discrete three dimensional Gradgrad-complexes consisting of finite element spaces is constructed. These discrete complexes are exact in the sense that the range of each discrete map is the kernel space of the succeeding one. These spaces can be used in the mixed form of the linearized Einstein-Bianchi system.

在三个维度上使离散Gradgrad复合体符合

摘要：本文构建了由有限元空间组成的第一类一致的离散三维Gradgrad复合体。这些离散复合体在每个离散映射的范围是后续映射的内核空间的意义上是精确的。这些空间可以线性爱因斯坦-比安奇系统的混合形式使用。
