Abstract:

In this paper we prove that there are infinitely many abelian left symmetric algebras in dimensions $\geq 6$. Equivalently this means that there are, up to affine conjugation, infinitely many simply transitive affine actions of $\mathbb R^k$, for $k\geq 6$. This is a result which is usually credited to A.T. Vasquez, but for which there is no proof in the literature.
