| Jul 7, 2022 at 14:15 | comment | added | Eric Peterson | They’re fairly common: every suspension spectrum gives a comonoid, and a lesser known theorem of Bousfield says that in the K(n)-local category every spectrum admits such a structure. The “Thom diagonal” is an adjacent concept, presenting a Thom spectrum as a cotorsor for the comonoid associated to the suspension spectrum of the base space. I don’t know whether there’s an out-and-out classification available. | |
