Random Geometric Structures
In the first part, we use a stationary Poisson point process to construct two random simplicial complexes, the random Vietoris-Rips complex and the random Cech complex, that are rich enough to realize any compact topological manifold, at least up to homotopy equivalence.
In the second part, we investigate the random Vietoris-Rips complex constructed from a stationary Poisson point process on a d-dimensional compact set using the uniform norm.
Opposed to most of the existing literature in which the focus lies on random geometric graphs in the fixed dimensional case, we will generalize this model by investigating the asymptotic distributional behavior of the f-vector if the intensity as well as the space dimension d tend to infinity simultaneously.
It turns out, that the phase-transition phenomenon occurs also in the components of the f-vector of the random Vietoris-Rips complex in the fixed and high-dimensional cases.
