A problem on generalized quadrangles

Journal of Statistical Planning and Inference, 1998
Let \({\mathcal S}=(P,B,I)\) be a generalized quadrangle of order \((s,t)\), \(s>1\), \(t>1\). Let \(p\) be a distinguished point of \(\mathcal S\) and \(G\) a group of collineations of \(\mathcal S\) acting regularly on the \(s^2t\) points of \(P-p^\bot\). In this case \(({\mathcal S}_p,G)\) is called a homogeneous generalized quadrangle (HGQ). If \(G\

Translation generalized quadrangles

Archiv der Mathematik, 1996
A translation generalized quadrangle (TGQ) is a generalized quadrangle admitting a (uniquely determined) abelian group \(T\) of collineations fixing each line passing through some point \(\infty\) and acting transitively (and therefore regularly) on the set of points opposite to \(\infty\). Finite TGQ have been introduced by \textit{J. A. Thas} in Atti

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).

Coordinatization of Generalized Quadrangles

1988
Publisher Summary This chapter discusses a coordinatization method for any thick generalized quadrangle (GQ) using a new algebraic structure—that is, a quadratic quaternary ring. A generalized quadrangle is an incidence structure S = (P, L, I) with point set P and line set L, satisfying the following axioms: (1) each point is incident with 1 + t ...
