The circle action on topological Hochschild homology of complex cobordism and the Brown-Peterson spectrum

John Rognes

We specify exterior generators for ${\pi }_{\ast }THH(MU)={\pi }_{\ast }(MU)\otimes E({\lambda }_n^{\prime }\mid n\ge 1)$ and ${\pi }_{\ast }THH(BP)={\pi }_{\ast }(BP)\otimes E({\lambda }_n\mid n\ge 1)$, and calculate the action of the $\sigma$-ope…
