Linking Forms, Singularities, and Homological Stability for Diffeomorphism Groups of Odd Dimensional Manifolds

Let n > 1. We prove a homological stability theorem for the

diffeomorphism groups of (4n+1)-dimensional manifolds, with respect

to forming the connected sum with (2n-1)-connected,

(4n+1)-dimensional manifolds that are stably parallelizable.

Our techniques involve the study of the action of the diffeomorphism group of a manifold M on the linking form associated to the homology groups of M.

In order to study this action we construct a geometric model for the linking form using the intersections of embedded and immersed Z/k-manifolds.

In addition to our main homological stability theorem, we prove several results regarding disjunction for embeddings and immersions of Z/k-manifolds that could be of independent interest.
