Abstract:
A normal quasi-affine surface over an algebraically closed field of characteristic zero which has a ${G_a}$-action is shown to have a geometric quotient if and only if the action is without fixed points. If the surface is factorial affine, and the action without fixed points, the surface is the product of a curve and ${G_a}$.References
