Abstract

In the article of Hesselholt [Hes05], a set of conjectures is laid out. Given a smooth scheme XX over the ring of integers OK\mathcal{O}_K of a pp-adic field KK, these conjectures concern the expected relation between log topological restriction homology TRr(X,MX)\mathrm{TR}^r (X,M_X) and the absolute log de Rham--Witt complex WrΩ(X,MX)W_r\Omega_{(X,M_X)}. In this note, which is companion to [And24a], we discuss the case of a pp-completely smooth pp-adic formal scheme XX over spfOC\mathrm{spf} \mathcal{O}_C, where CC is the field of pp-adic complex numbers. Along the way, we study the motivic filtration of log TRr\mathrm{TR}^r and its S1S^1-homotopy fixed points, following ideas of [Bin+23].
