Groups of Projectivities of Generalized Quadrangles

Geometriae Dedicata, 1998
For some reason the study of groups of projectivities of generalized quadrangles did not yet receive the attention due, although the study of groups of projectivities of projective planes produced a number of remarkable classification results. This paper rights this wrong.

Generalized quadrangles with valuation

Geometriae Dedicata, 1990
We show that the class of generalized quadranges with valuation (as defined in [13]) coincides with the class of the generalized quadrangles associated with the building at infinity of affine buildings of type \(\tilde C_2\) (up to duality).

Classical Klingenberg generalized quadrangles

Archiv der Mathematik, 1990
A Klingenberg generalized quadrangle is an incidence structure with neighbour relation having an ordinary generalized quadrangle as epimorphic image. Some infinite classes of examples are obtained using polarities in projective Klingenberg spaces.

Moufang conditions for finite generalized quadrangles

1981
Publisher Summary This chapter discusses the Moufang conditions for finite generalized quadrangles. The chapter reviews the efforts for finding an “elementary” proof of Tits' theorem. The chapter also discusses the Moufang conditions and property and the elimination of case.

Span-Symmetric Generalized Quadrangles

1981
A generalized quadrangle (GQ) of order (s,t) is a point-line incidence geometry S = (P,L,I) with pointset P, lineset L and incidence relation I satisfying the following: (1) Two points are incident with at most one line in common. (2) If x ∈ P, L ∈ L, and x I L (i.e.
