**Sets, groups, and fields definable in vector spaces with a bilinear form.**

Abstract:

There is a long history of study of algebraic objects definable in classical mathematical structures.

As a prominent example, by results of Weil, Hrushovski, and van den Dries, it is known that the groups definable in an algebraically closed field K are precisely the algebraic groups over K, and the only infinite field definable in K is the field K itself.
