J. Scholbach: The intersection cohomology motive of the moduli stack of shtukas (Mittagsseminar zur Arithmetik)
Dienstag, 11.12.2018 10:00 im Raum SR 1C
In these talks, I will report on joint work with Timo Richarz. We construct a motivic refinement of various intersection complexes on the moduli stack of G-shtukas used in the work of V. Lafforgue. In the first talk, I will present a short introduction to motives and will present tools for working with motives on infinite-dimensional objects. The second talk will be about t-structures on stratified Tate motives and their application to the mentioned intersection complexes.
