On quadratic coalgebras, duality and the universal Steenrod algebra
Geoffrey Powell
The notion of quadratic self-duality for coalgebras is developed with applications to algebraic structures which arise naturally in algebraic topology, related to the universal Ste…
Embedding the flag representation in divided powers
Geoffrey Powell
A generalization of a theorem of Crabb and Hubbuck concerning the embedding of flag representations in divided powers is given, working over an arbitrary finite field F, using the…
Subrings of singular cohomology associated to spectra
Geoffrey M L Powell
This paper extends the relation established for group cohomology by Green, Hunton and Schuster between chromatic phenomena in stable homotopy theory and certain natural subrings of…
Unstable modules over the Steenrod algebra revisited
Geoffrey M L Powell
A new and natural description of the category of unstable modules over the Steenrod algebra as a category of comodules over a bialgebra is given; the theory extends and unifies the…
