The authors provide important definitions and theorems on critical edges, local minima, and selective Rips complexes, and caution that certain assumptions are necessary for their results to hold. #Topology #RipsComplexes #PersistentHomology #ComputerScience #TopologicalDataAnalysis

To compute #PersistentHomology, one needs to check, for each d-simplex σi of a filtration, if it "fills" a (d-1)-dimensional hole, i.e. if its boundary ∂σi is homologous to a non-trivial (d-1)-cycle created on an unpaired (d-1)-simplex (blue).

Two p-cycles a and b are "homologous" (i.e. belong to the same #Homology class) if there exists a (p+1)-chain c, such that b = a + ∂c (mod-2 sum)

Topological persistence is an importance measure in #PersistentHomology, with a strong practical utility for noise removal in various applications: #Imaging, #Clustering, #ClimateScience, #Geophysics, #MaterialScience and more! 👇
