Subdivisional Spaces and Graph Braid Groups
Documenta mathematica, Tome 24 (2019), pp. 1513-1583
We study the problem of computing the homology of the configuration spaces of a finite cell complex X. We proceed by viewing X, together with its subdivisions, as a subdivisional space – a kind of diagram object in a category of cell complexes. After developing a version of Morse theory for subdivisional spaces, we decompose X and show that the homology of the configuration spaces of X is computed by the derived tensor product of the Morse complexes of the pieces of the decomposition, an analogue of the monoidal excision property of factorization homology.
