Discrete Gravity with Local Lorentz Invariance
Eugene KurAlexander S. Glasser
文献摘要
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.
