Formal Groups and the Secondary Steenrod algebra

Status: whatever


The goal is to give a description of H.J.Baues' "secondary Steenrod algebra" in terms of formal group laws.

Project details

Baues' secondary Steenrod algebra is a certain 4-term exact sequence of the form
A → B1 → B0 → A
where A is the ordinary Steenrod algebra. I have described a smaller but equivalent model in my paper. This model does not yet have a good explanation, though. I wonder if some notion of "formal group up-to-homotopy" could be used to give a natural & convincing description of it.
