Abstract

Random simplicial complexes, as generalizations of random graphs, have become increasingly popular in the literature in recent years. In this paper, we consider a new model for a random simplicial complex that was introduced in [1], which generalizes the Random Connection Model (RCM) in a natural way and includes several models used in the literature as special cases. We focus on the marked stationary case with vertices in Rd×A, where the mark space A is an arbitrary Borel space. We will derive a central limit theorem (CLT) for an abstract class of functionals and show that many of the typical functionals considered in the study of simplicial complexes, such as Betti numbers, fall into this class. As an important special case, we obtain a CLT for Betti numbers in the Boolean model.
