Abstract

Let K\mathbb{K} be an algebraically closed field of characteristic zero and Ga\mathbb{G}_a be the additive group of K\mathbb{K}. We say that an irreducible algebraic variety XX of dimension nn over the field K\mathbb{K} admits an additive action if there is a regular action of the group Gan=Ga××Ga\mathbb{G}_a^n = \mathbb{G}_a \times \ldots \times \mathbb{G}_a (nn times) on XX with an open orbit. In this paper we find all projective toric hypersurfaces admitting additive action.
