In this paper we study the homology of a random Čech complex generated by a homogeneous Poisson process in a compact Riemannian manifold M . In particular, we focus on the phase transition for “homological connectivity” where the homology of the complex becomes isomorphic to that of M . The results presented in this paper are an important generalization of [7][O. Bobrowski, 2017], from the flat torus to general compact Riemannian manifolds. In addition to proving the statements related to homological connectivity, the methods we develop in this paper can be used as a framework for translating results for random geometric graphs and complexes from the Euclidean setting into the more general Riemannian one.
