Projective normality of quotient varieties modulo finite groups

Abstract

In this note, we prove that for any finite dimensional vector space $V$ over an algebraically closed field $k$, and for any finite subgroup $G$ of $GL(V)$ which is either solvable or is generated by pseudo reflections such that the $|G|$ is a unit in $k$, the projective variety $\mathbb{P}(V)/G$ is projectively normal with respect to the descent of $\mathcal{O}(1{)}^{\otimes |G|}$.
