SoSe 26 Oberseminar: Motivic cohomology of schemes

Time and place: Tuesday 14-16 in M311 and online

The goal of this seminar is to understand the motivic filtration of the A¹-invariant algebraic K-theory of arbitrary schemes and the resulting theory of A¹-invariant motivic cohomology, recently developed in this generality by Bachmann, Elmanto, and Morrow. The construction uses many aspects of the formalism of motivic spectra, including the slice filtration, the six-functor formalism, and framed correspondences, which we will review. We will then discuss the comparison with cycle-theoretic constructions in special cases (for smooth schemes over Dedekind rings) and with syntomic cohomology (the Beilinson–Lichtenbaum conjecture), and compute motivic cohomology in low weights.
