Affinity criterion for the quotient of an algebraic group by a one-dimensional subgroup
Abstract
In this work we show that the homogeneous space of an affine algebraic group $G$ by a one-dimensional unipotent subgroup $H$ is affine if and only if the subgroup is not contained in any reductive subgroup of $G$.
