Abstract
Our goal is to classify all generically transitive actions of commutative unipotent groups on flag varieties up to conjugation. We establish a relationship between this problem and the classification of multiplications with certain properties on Lie algebra representations. Then we classify multiplications with the desired properties and solve the initial classification problem.
