On images of affine spaces
Abstract:We prove that every non-degenerate toric variety, every homogeneous space of a connected linear algebraic group without non-constant invertible regular functions, and every variety covered by affine spaces admit a surjective morphism from an affine space.
Keywords:Affine space  Morphism  Image  Unirational variety  Invertible function  Flexible variety  Toric variety  Homogeneous space
