Abstract
Let G be a simple, simply connected algebraic group of exceptional type defined over Fq with Frobenius endomorphism F:G→G. Let ℓ∤q be a good prime for G. We determine the number of irreducible Brauer characters in the quasi-isolated ℓ-blocks of GF. This is done by proving that generalized e-Harish-Chandra theory holds for the Lusztig series associated to quasi-isolated elements of G⁎F.
