Abstract
In this work, we give two characterisations of the general linear group as a group of finite Morley rank acting on an abelian connected group of finite Morley rank definably, faithfully and irreducibly. To be more precise, we prove that if the pseudoreflection rank of is equal to the Morley rank of , then has a vector space structure over an algebraically closed field, and the action is the natural action. The same result holds also under the assumption of Prufer 2-rank of being equal to the Morley rank of .
