Non-tame Morse-Smale flows and odd Chern-Weil theory

Using a certain well-posed ODE problem introduced by Shilnikov in the sixties, G. Minervini proved in his PhD thesis [17], among other things, the Harvey-Lawson Diagonal Theorem but without the restrictive tameness condition for Morse flows. Here we combine the same techniques with the ideas of Latschev in order to construct local resolutions for the flow of the graph of a section of a fiber bundle. This is endowed with a vertical vector field which is horizontally constant and Morse-Smale in every fiber. The resolution allows the removal of the tameness hypothesis from the homotopy formula in [3]. We give one finite and one infinite dimensional application. For that end, we introduce closed smooth forms of odd degree associated to any triple (E;U;\nabla) composed of a hermitian vector bundle, unitary endomorphism and metric compatible connection.
