Seminar: Algebra
Survey on recent results on maximal tori of algebraic groups
Philippe Gille, CNRS, Lyon
Contact: John Duncan, john.duncan@emory.edu
Venue: Mathematics and Science Center, Room W306
Prasad and Rapinchuk investigated the isopectrality problem for certain Riemannian varieties by analysing in what extent a semisimple algebraic group defined over a number field is determined by its maximal tori. We shall report advances on this topic by Chernousov/Rapinchuk/Rapinchuk, Bayer-Fluckiger/Lee/Parimala and others by discussing the case of non-archimedean fields and local-global principles.
