Group actions on twin buildings
Though parts of the present paper perfectly look like abstract general nonsense, its origin is a rather concrete question. Given a simply connected almost simple Chevalley group G and a field k, what is a fundamental domain (in an appropriate sense) for the action of G(k[t, t−1]) on the product ∆+ × ∆− of the two associated Bruhat–Tits buildings ∆+ = ∆(G(k((t−1)))) and ∆− = ∆(G(k((t)))) ? The s...
متن کاملTransitivity Properties for Group Actions on Buildings
We study two transitivity properties for group actions on buildings, called Weyl transitivity and strong transitivity. Following hints by Tits, we give examples involving anisotropic algebraic groups to show that strong transitivity is strictly stronger than Weyl transitivity. A surprising feature of the examples is that strong transitivity holds more often than expected.
متن کاملMoufang Buildings and Twin Buildings
The “Moufang Condition” for spherical buildings was introduced by J. Tits in the appendix of [9], as a tool to give more structure to the classification of spherical buildings of rank at least three (which are automatically “Moufang”). More recently, also the spherical buildings of rank 2 satisfying the Moufang Condition are classified [13]. Hence one could say that, on the geometric level, sph...
متن کاملAffine twin R-buildings
In this paper, we define twinnings for affine R-buildings. We thus extend the theory of simplicial twin buildings of affine type to the non-simplicial case. We show how classical results can be extended to the non-discrete case, and, as an application, we prove that the buildings at infinity of aMoufang twin R-building have the induced structure of aMoufang building. The latter is not true for ...
متن کاملLoop Groups and Twin Buildings
In these notes we describe some buildings related to complex Kac-Moody groups. First we describe the spherical building of SLn(C) (i.e. the projective geometry PG(Cn)) and its Veronese representation. Next we recall the construction of the affine building associated to a discrete valuation on the rational function field C(z). Then we describe the same building in terms of complex Laurent polyno...
