We prove that the unipotent horocyclic group of a Moufang twin tree of prime order is nilpotent of class at most 2.
Angle-deformations in Coxeter groups
Timothée Marquis, Bernhard Mühlherr
The isomorphism problem for Coxeter groups has been reduced to its 'reflection preserving version' by B. Howlett and the second author. Thus, in order to solve it, it suffices to d…
The isomorphism problem for Coxeter groups
