REGULAR CYCLIC ACTIONS ON COMPLEX PROJECTIVE SPACE WITH CODIMENSION-TWO FIXED POINTS

If M2n is a cohomology CPn and p is an odd prime, let Gp be the cyclic group of order p. A Type I I0 Gp action on M2n is an action with fixed point set a codimension-2 submanifold and an isolated point. A Type I I0 Gp action is standard if it is regular and the degree of the fixed codimension-2 submanifold is one. If n is odd and M2n admits a standard Gp action of Type I I0, then every Type I I0 Gp action on M2n is standard and so, if n is odd, CPn admits a Gp action of Type I I0 if and only if the action is standard
