Published online by Cambridge University Press: 20 November 2018
Abstract
We show that over a field k of characteristic zero an affine (n — 1)- space embedded as a closed subvariety in affine n-space
and homogeneous for a codimension two linear torus action on
is defined by the vanishing of a variable.
