will speak on
Point regular automorphism groups of generalised quadrangles
at 12 noon on Tuesday 25 May in MLR2
Abstract: (joint work with John Bamberg) Studying regular automorphism groups of combinatorial objects has had a long history. Recently there has been some focus on groups of automorphisms of generalised quadrangles that act regularly on the set of points. In this talk I will give a classification of all point regular automorphism groups of the thick classical generalised quadrangles. I will also construct point regular automorphism groups of some nonclassical generalised quadrangles. The constructions show that the class of groups which can act regularly on the set of points of a generalised quadrangle contains nonabelian 2-groups, groups of exponent 9 and nonspecial p-groups, and is thus wilder than previously thought.
All welcome.
