Abstract:

The mod 2 Steenrod algebra $\mathcal {A}$ and Dyer-Lashof algebra $\mathcal {R}$ have both striking similarities and differences arising from their common origins in “lower-indexed” algebraic operations. These algebraic operations and their relations generate a bigraded bialgebra $\mathcal {K}$, whose module actions are equivalent to, but quite different from, those of $\mathcal {A}$ and $\mathcal {R}$. The exact relationships emerge as “sheared algebra bijections”, which also illuminate the role of the cohomology of $\mathcal {K}$. As a bialgebra, $\mathcal {K}^{*}$ has a particularly attractive and potentially useful structure, providing a bridge between those of $\mathcal {A^{*}}$ and $\mathcal {R^{*}}$, and suggesting possible applications to the Miller spectral sequence and the $\mathcal {A}$ structure of Dickson algebras.
