SUMMARY:Colloquium: Zev Rosengarten (HUJI) - Moduli Spaces of Morphisms Into Algebraic Groups
DESCRIPTION:*Link for online \nwatching*:https://huji.cloud.panopto.eu/Panopto/Pages/Viewer.aspx?id=48dafdfd-15f1-4433-86ce-adbc006e1300 \n[1]*\n*\n*\n*\n*Title:* Moduli Spaces of Morphisms Into Algebraic Groups\n*Abstract:* For a pair of (quasi-projective) varieties X and Y over some \nfield k, the functor Mor(X, Y) of morphisms from X to Y is representable when \nX is projective. If one relaxes the projectivity assumption on X (say, if X \nis affine), this usually fails completely. Nevertheless, we will show that, \nin great generality, this moduli spaceis representable in a suitable sense \nwhen Y is a solvable algebraic group, with special emphasis on the case in \nwhich k is imperfect and Y is (wound) unipotent. As an application, we will \nshow that one of the main results of geometric class field theory remains \ntrue after base change by a geometrically reduced variety. All of the \nimportant concepts will be introduced in the talk, with minimal background \nknowledge required.\n\n[1] https://huji.cloud.panopto.eu/Panopto/Pages/...
