EHTW03 - New horizons for equivariance in homotopy theory

We first review some of the developments about TR and the cyclotomic t-structure on it. Then we explain how to define a relative version of TR and prove a generalization of a theorem of Hesselholt—Madsen relating it to the derived de Rham Witt complex. If time permits, we also indicate how to generalize this to an integral story and how to give an algebraic description using relative prismatic cohomology.
