论文摘要
一种新型的实现真空中总体相对性的结构保存算法是从四个palatini作用的晶格理论离散化得出的。证明所得的离散重力模型可以保留局部洛伦兹的不变性和符号结构。
A novel structure-preserving algorithm for general relativity in vacuum is derived from a lattice gauge theoretic discretization of the tetradic Palatini action. The resulting model of discrete gravity is demonstrated to preserve local Lorentz invariance and symplectic structure.
