Abstract:

Let ${M^{2n}}$ be a smooth, closed, orientable $2n$-manifold and suppose that $K_x^{2n - 2}$ is an orientable submanifold of ${M^{2n}}$ dual to a cohomology class $x$. If $d$ is a positive integer, the signatures of $K_{dx}^{2n - 2}$ and $K_x^{2n - 2}$ are related by a numerical congruence. If $n$ is odd, then any codimension 2 submanifold of ${\mathbf {C}}{P^n}$ fixed by a diffeomorphism of odd prime order is dual to the generator of the cohomology algebra.
