Computing Topological Persistence for Simplicial Maps
Tamal K. Dey, Fengtao Fan, Yusu Wang · 2014
Algorithms for persistent homology are well-studied where homomorphisms are induced by inclusion maps. In this paper, we propose a practical algorithm for computing persistence under Z2 coefficients for a (monotone) sequence of general simplicial maps and show how these maps arise naturally in some applications of topological data analysis.
