The $\mathbb{Z}$-homotopy fixed points of $C_n$ spectra with applications to norms of $M{U}_{\mathbb{R}}$

Michael A. Hill, Mingcong Zeng

We introduce a computationally tractable way to describe the $\mathbb{Z}$-homotopy fixed points of a $C_n$-spectrum $E$, producing a genuine $C_n$ spectrum $E^{hn\mathbb{Z}}$ who…
