WebJun 6, 2016 · Abstract We prove a 1979 conjecture of Lusztig on the cohomology of semi-infinite Deligne–Lusztig varieties attached to division algebras over local fields. We also prove the two conjectures of Boyarchenko on these varieties. It is known that in this setting, the semi-infinite Deligne–Lusztig varieties are ind-schemes comprised of limits of … WebParts 5 and 6 are concerned with the modular representation theory of finite groups of Lie type in non-defining characteristicℓ.
