Automorphisms of Lie incidence geometries with spectral gaps
Yannick Neyt, James Parkinson, Hendrik Van Maldeghem
An automorphism of a building is called uniclass if the Weyl distance between any chamber and its image lies in a unique (twisted) conjugacy class of the Coxeter group. In a previo…
Uniclass automorphisms of spherical buildings
Yannick Neyt, James Parkinson, Hendrik Van Maldeghem
An automorphism of a building is called uniclass if the Weyl distance between any chamber and its image lies in a single (twisted) conjugacy class of the Coxeter group. In this pap…
Automorphisms and opposition in spherical buildings of exceptional type, IV: The case
Yannick Neyt, James Parkinson, Hendrik Van Maldeghem +1
An automorphism of a spherical building is called \textit{domestic} if it maps no chamber onto an opposite chamber. This paper forms a significant part of a large project classifyi…
Local recognition of the point graphs of some Lie incidence geometries
Ferdinand Ihringer, Paulien Jansen, Linde Lambrecht +4
Given a finite Lie incidence geometry which is either a polar space of rank at least or a strong parapolar space of symplectic rank at least and diameter at most , or th…
