Primitive permutation groups of finite Morley rank and affine type

Abstract

We give a review of one of the lines in development of the theory of groups of finite Morley rank. These groups naturally appear in model theory as model-theoretic analogues of Galois groups, therefore their actions and their role as permutation groups is of primary interest. We restrict our story to the study of connected groups of finite Morley rank GG acting in a definably primitive way on a set XX and containing a definable abelian normal subgroup VV which acts on XX regularly -- the so-called \emph{primitive groups of affine type}. For reasons explained in the paper, this case plays a central role in the theory.
