Unstable algebras over an operad II
arXiv:2011.13002
Abstract
We introduce a notion of unstable algebra over an operad in general characteristic. We show that the unstable algebra freely generated by an unstable module is itself a free algebra under suitable conditions. We introduce a family of '-level' operads which allows us to identify unstable modules studied by Brown--Gitler, Miller and Carlsson to free unstable -level algebras.
