	"Biaffine geometries, amalgams and group recognition"
	A polar space $\Pi$ is a geometry whose elements are the totally isotropic subspaces of a vector space $V$ with respect to either an alternating, Hermitian, or quadratic form. We may form a new geometry $\Gamma$ by removing all elements contained in either a hyperplane $F$ of $\Pi$ , or a hyperplane $H$ of the dual $\Pi^$ . This is a biaffine polar space*. We will discuss two specific examples, one with automorphism group $q^6:SU_3(q)$ and the other $G_2(q)$ . By considering the stabilisers of a maximal flag, we get an amalgam, or "glueing", of groups for each example. However, the two examples have "similar" amalgams - this leads to a group recognition result for their automorphism groups.
