Veldkamp quadrangles and polar spaces
Richard M. Weiss, Bernhard Mühlherr
Veldkamp polygons are certain graphs such that for each , is endowed with a symmetric anti-reflexive relation . These relations are all trivial if…
Tits Endomorphisms and Buildings of Type
Tom De Medts, Yoav Segev, Richard M. Weiss
The fixed point building of a polarity of a Moufang quadrangle of type is a Moufang set, as is the fixed point building of a semi-linear automorphism of order of a Moufan…
Webs of Lagrangian Tori in Projective Symplectic Manifolds
Jun-Muk Hwang, Richard M. Weiss
For a Lagrangian torus A in a simply-connected projective symplectic manifold M, we prove that M has a hypersurface disjoint from a deformation of A. This implies that a Lagrangian…
The Kneser-Tits conjecture for groups with Tits-index E_{8,2}^{66} over an arbitrary field
R. Parimala, J. -P. Tignol, R. M. Weiss
We prove: (1) The group of multipliers of similitudes of a 12-dimensional anisotropic quadratic form over a field K with trivial discriminant and split Clifford invariant is genera…
Compact Totally Disconnected Moufang Buildings
Theo Grundhofer, Linus Kramer, Hendrik Van Maldeghem +1
Let be a spherical building each of whose irreducible components is infinite, has rank at least 2 and satisfies the Moufang condition. We show that can be given the structu…
The norm of a Ree group
Tom De Medts, Richard M. Weiss
We give an explicit construction of the Ree groups of type as groups acting on mixed Moufang hexagons together with detailed proofs of the basic properties of these groups co…
