Braid groups of normalizers of reflection subgroups
Thomas Gobet, Anthony Henderson, Ivan Marin
Let be a reflection subgroup of a finite complex reflection group , and let and be their respective braid groups. In order to construct a Hecke algebra $\widetil…
Involutions on the affine Grassmannian and moduli spaces of principal bundles
Anthony Henderson
Let be a simply connected semisimple group over . We show that a certain involution of an open subset of the affine Grassmannian of , defined previously by Achar…
Modular generalized Springer correspondence: an overview
Pramod N. Achar, Anthony Henderson, Daniel Juteau +1
This is an overview of our series of papers on the modular generalized Springer correspondence. It is an expansion of a lecture given by the second author in the Fifth Conference o…
Modular generalized Springer correspondence III: exceptional groups
Pramod N. Achar, Anthony Henderson, Daniel Juteau +1
We complete the construction of the modular generalized Springer correspondence for an arbitrary connected reductive group, with a uniform proof of the disjointness of induction se…
Singularities of nilpotent orbit closures
Anthony Henderson
This is an expository article on the singularities of nilpotent orbit closures in simple Lie algebras over the complex numbers. It is slanted towards aspects that are relevant for…
Modular generalized Springer correspondence II: classical groups
Pramod N. Achar, Anthony Henderson, Daniel Juteau +1
We construct a modular generalized Springer correspondence for any classical group, by generalizing to the modular setting various results of Lusztig in the case of characteristic-…
