Titles and abstracts

Akhil Mathew (Chicago): On K(1)-local TR
Abstract: The K(1)-localization of algebraic K-theory was first studied by Thomason, who showed that it is filtered by étale cohomology under mild hypotheses. Using some recent advances in the theory of topological Hochschild homology and cyclotomic spectra, I will explain some general properties of K(1)-local TR and an analog of Thomason's result in this context.

Doosung Park (Zurich): Triangulated categories of logarithmic motives over a field

Abstract: There are many non A1-invariant cohomology theories like Hodge cohomology theories. To incorporate these in the framework of triangulated categories of motives, we can instead use a compactification of A1 in logarithmic geometry, which we call Cube. One technical problem is that Cube does not admit a multiplication map, so Cube is not an interval object in the sense of Morel and Voevodsky. In particular, the naive Sing functor is not useful. In this talk, I will explain how to construct a Sing functor for Cube that can be used to compare Voevodsky's motives and logarithmic motives.
