Exceptional motives and exceptional local systems
Abstract: In 1996, Serre asked about the existence of motives with exceptional motivic Galois group. Such motives are now known to exist for all exceptional groups, due to work of Gross--Savin, Katz, Dettweiler--Reiter, Yun, Patrikis, Boxer--Calegari--Emerton--Levin--Patrikis--Madapusi Pera, Guralnick--Lubeck--Yu, and Faegerman (and possibly others). For all exceptional groups except \(E_6\), families of such motives were known, but until recently this was open for \(E_6\). I'll survey this story, explain joint work with Krämer--Maculan constructing families of exceptional \(E_6\)-motives---arising from the classical geometry of cubic \(3\)-folds---and speculate about similar constructions for other exceptional groups.
