An average intersection estimate for families of diffeomorphisms

Differential Geometry 2024-03-27 v1 Dynamical Systems

Abstract

We show that for any sufficiently rich compact family H\mathcal{H} of C1C^1 diffeomorphisms of a closed Riemannanian manifold MM, the average geometric intersection number over hHh \in \mathcal{H} between h(V)h(V) and WW, for V,WV, W any complementary dimensional submanifolds of MM, is approximately (i.e. up to a uniform multiplicative error depending only on H\mathcal{H}) the product of their volumes. We also give a construction showing that such families always exist.
