Scalar Curvature Invariants in Classical and Quantum Gravity
arXiv:2106.05926
Abstract
A short review of scalar curvature invariants in gravity theories is presented. We introduce how these invariants are constructed and discuss the minimal number of invariants required for a given spacetime. We then discuss applications of these invariants and focus on three topics that are of particular interest in modern gravity theories.
