$\omega$-stability and Morley rank of bilinear maps, rings and nilpotent   groups
  In this paper we study the algebraic structure of $\omega$-stable bilinear maps, arbitrary rings and nilpotent groups. We will also provide rather complete structure theorems for the above structures in the finite Morley rank case.
