SUMMARY:Workshop / Seminar:Student Number Theory: Character sheaves for unipotent groups & easy algebraic groups
DESCRIPTION:An algebraic group is called \"easy\" if every geometric point is contained in the neutral connected component of its centralizer. In 2006\, Boyarchenko and Drinfeld conjectured that a unipotent group is easy if and only if its L-packets of character sheaves are singletons. In 2013\, Boyarchenko proved the \"only if\" direction. In this talk\, we sketch a proof of the converse. Along the way\, we give a characterization of easy algebraic groups via their Asai twisting operators. No prior knowledge of character sheaves is assumed.
