Generic intersections of differentiable submanifolds
Abstract: Consider a transitive action of a Lie group $G$ on a (real analytic) manifold $M$ of dimension $m$, and two (embedded) submanifolds $A$ and $B$ in $M$ of sufficiently large class and of dimension $k$ and $l$, respectively. We prove that, for a generic $\sigma \in G$, the intersection $\sigma (A) \cap B$ is transversal, whence a submanifold of dimension $k+l-m$ or the empty set. This paper is a continuation of our previous article, devoted to definable transitive actions of definable groups on manifolds and generic intersections in an o-minimal structure, and inspired by a question of Jan Mycielski about the intersections of translates of analytic sets in the real plane.
