title = "On semifree symplectic circle actions with isolated fixed points",
abstract = "Let M be a symplectic manifold, equipped with a semi-free symplectic circle action with a finite, non-empty fixed point set. We show that the circle action must be Hamiltonian, and M must have the equivariant cohomology and Chern classes of (P1)n.",
