Leray Spectral Sequence for Simplicial Maps

Algebraic Topology 2019-12-19 v1

Abstract

The Leray spectral sequence of a map ff computes the homology of the domain of ff from the fibers of ff. In this expository paper, we relate in full detail the Leray spectral sequence associated to a simplicial map ff to the Leray cosheaves of ff. We then give applications to level set persistent homology and Reeb spaces.
