In this paper we give a combinatorial characterization of projections ofgeodesics in Euclidean buildings to Weyl chambers. We apply these results to the representation theory of complex reductive Lie ...
In this paper we apply our results on the geometry of polygons in infinitesimal symmetric spaces, symmetric spaces and buildings, [KLM1, KLM2], to four problems in algebraic group theory. Two of these...
Let G denote a connected reductive group, de ned and split over Z, and let M  G denote a Levi subgroup. In this paper we study varieties of geodesic triangles with xed vector-valued side-lengths ...
Let X be a symmetric space of non-compact type or a locally finite, strongly transitive Euclidean building, and let B denote the geodesic boundary of X. We reduce the study of visual limits of maximal...
This survey is a brief introduction to the theory of hyperbolic buildings and their lattices, with a focus on recent results.
Abstract: In this paper we classify the the epimorphisms of irreducible spherical Moufang buildings (of rank at least 2) defined over a field. As an application we characterize indecomposable epimorph...
Abstract: We construct and classify all groups acting simply transitively on vertices of hyperbolic triangular buildings of the smallest non-trivial thickness. We have both torsion and torsion free gr...
This is a survey on nondiscrete euclidean buildings, with a focus on metric properties of these spaces.
We classify flips of buildings arising from non-degenerate unitary spaces of dimen-sion at least 4 over finite fields of odd characteristic in terms of their action on the underlying vector space. We ...
For an arbitrary Euclidean building we define a certain combing, which satisfies the `fellow traveller property' and admits a recursive definition. Using this combing we prove that any group acting f...
We prove that every open subset of a euclidean building is a finite dimensional absolute neighborhood retract. This implies in particular that such a set has the homotopy type of a finite dimensional ...
The motivation for this note is the Center Conjecture for spherical buildings,which states the following: Let  be a spherical building and a convex subcomplex.
We give the generalized triangle inequalities which determine the possible -valued side lengths of n-gons in thick Euclidean buildings of rank 2.
Let 􀀀 be a non-cocompact lattice on a locally finite regular right-angled building X. We prove that if 􀀀 has a strict fundamental domain then 􀀀 is not finitely generated. We...
