Abstract:
In this work we shall consider smooth semifree (i.e., free outside the fixed point set) actions of ${{\mathbf {S}}^3}$ on a manifold $M$. We exhibit a Gysin sequence relating the cohomology of $M$ with the intersection cohomology of the orbit space $M/{{\mathbf {S}}^3}$. This generalizes the usual Gysin sequence associated with a free action of ${{\mathbf {S}}^3}$.References
