If you have a question about this talk, please contact Lewis Topley. In joint work with Segal we use the fact that for Chevalley groups G( R ) of rank at least 2 over a ring R the root subgroups are (nearly always) the double centralizer of a corresponding root element to show for many important classes of rings and fields that R and G( R ) are bi-interpretable. For such groups it then follows that the group G( R ) is finitely axiomatizable in the appropriate class of groups provided R is finitely axiomatizable in the corresponding class of rings.
