Commutativity properties of Quinn spectra
Commutativity properties of Quinn spectra
We give a simple sufficient condition for Quinnās ābordism-typeā spectra to be weakly equivalent to commutative symmetric ring spectra. We also show that the symmetric signature is (up to weak equivalence) a monoidal transformation between symmetric monoidal functors, which implies that the SullivanāRanicki orientation of topological bundles is represented by ā¦
