Flowing from intersection product to cup product
Greg Friedman, Anibal M. Medina-Mardones, Dev Sinha
We use a vector field flow defined through a cubulation of a closed manifold to reconcile the partially defined commutative product on geometric cochains with the standard cup prod…

Two short proofs of the topological invariance of intersection homology
Greg Friedman
We indicate two short proofs of the Goresky-MacPherson topological invariance of intersection homology. One proof is very short but requires the Goresky-MacPherson support and cosu…
