3-spherical twin buildings
Sebastian Bischof
We classify thick irreducible 3-spherical twin buildings of rank at least 3 in which every panel contains at least 6 chambers. Together with the Main result of [11] we obtain a cla…
Isometries of wall-connected twin buildings
Sebastian Bischof, Bernhard Mühlherr
We introduce the notion of a wall-connected twin building and show that the local-to-global principle holds for these twin buildings. As each twin building satisfying Condition (co…
On isometries of twin buildings
Sebastian Bischof, Anton Chosson, Bernhard Mühlherr
A twin building consists of two buildings that are twinned by a codistance function. We prove that the local structure of a twin building uniquely determines the two buildings up t…
On commutator relations in -spherical RGD-systems
Sebastian Bischof
In this paper we investigate the commutator relations for prenilpotent roots which are nested. These commutator relations are trivial in a lot of cases.
