Surjection operations provide an explicit and computable tool for expressing various operations from chains on a topological space X to  tensor powers of such chains. For example, this gives a procedure for computing Steenrod operations. In ongoing work with M. Levy, we lift surjection operations to chains in Cartesian powers of X. As an application, […]
