Lines and Opposition in Lie Incidence Geometries of Exceptional Type

Sira Busch, Hendrik Van Maldeghem

We characterise sets of points of exceptional Lie incidence geometries, that is, the natural geometries arising from spherical buildings of exceptional types , $\math…

A Characterization of Lines in Finite Lie Incidence Geometries of Classical Type

Sira Busch, Hendrik Van Maldeghem

We consider any classical Grassmannian geometry ; that is, any projective or polar Grassmann space. Suppose every line in contains points. Then we classify all sets of…
