Poisson Spacetime Discreteness and Unimodular Gravity: Consistency Conditions and Exact Past-Cone Statistics of a Fluctuating Cosmological Term in the TSGT Framework
Abstract Can Poisson discreteness of spacetime supply gravitational dynamics or a fluctuating cosmological term? We examine this question for the framework previously called Topological String-Gradient Theory (TSGT) and then make its statistical proposal quantitative. A random counting measure, its metric-dependent mea...
