Finite reconstruction with selective Rips complexes

Abstract

Selective Rips complexes corresponding to a sequence of parameters are a generalization of Vietoris-Rips complexes utilizing the idea of thin simplices. We prove that if a metric space YY is close (in Gromov-Hausdorff distance) to a closed Riemannian manifold XX, then selective Rips complexes of YY for certain parameters attain the homotopy type of XX. This result is a generalization of Latchev's reconstruction result from Vietoris-Rips complexes to selective Rips complexes. In particular, we present a novel proof for the Latschev's theorem as a special case. We also present a functorial setting, which is new even in the case of Vietoris-Rips complexes.
