An Axiomatic Characterization of Steenrod's cup-$i$ Products

A. M. Medina-Mardones

Published 2018-10-15Version 1

We present axioms that determine the cup-$i$ products introduced explicitly by Steenrod up to isomorphism, and not just homotopy. As is well known, these products generalize the Alexander-Whitney cup product on cochains and induce the Steenrod squares in cohomology.
