Adams-type maps are not stable under composition

Algebraic Topology 2022-03-01 v1

Abstract

We give a simple counterexample to the plausible conjecture that Adams-type maps of ring spectra are stable under composition. We then show that over a field, this failure is quite extreme, as any map of E\mathbb{E}_{\infty}-algebras is a transfinite composition of Adams-type maps.
