TC and syntomic cohomology Mathew, Akhil


I will describe some structural properties of the motivic filtration on topological cyclic homology constructed by Bhatt--Morrow--Scholze. In particular, I will describe an identification of the graded pieces (in low weights integrally and rationally in all weights) with syntomic cohomology, as introduced by Fontaine--Messing and Kato. Joint with Benjamin Antieau, Matthew Morrow, and Thomas Nikolaus.
