From the Thompson group to the hyperplanes in a dual polar space
Sergey Shpectorov (Birmingham), 16th October 2008
Abstract
A question about a configuration of subgroups
in the Thompson sporadic simple group leads to the study
of a particular subgeometry in a dual polar space. It turns
out this subgeometry belongs to a large intersecting class
of geometries which can be obtained by affinization,
i.e., removing a hyperplane.
