Root operators, root groups and retractions

Petra Schwer

We prove that the Gaussent--Littelmann root operators on galleries can be expressed purely in terms of retractions of a (Bruhat-Tits) building. In addition we establish a connectio…

Dimensions of affine Deligne-Lusztig varieties: a new approach via labeled folded alcove walks and root operators

Elizabeth Milićević, Petra Schwer, Anne Thomas

Let G be a reductive group over the field F=k((t)), where k is an algebraic closure of a finite field, and let W be the (extended) affine Weyl group of G. The associated affine Del…
