    Conceptually, the goal here is a construction which functorially translates a Hamiltonian fibre bundle to a certain ``derived vector bundle'' over the same space, with fiber an A∞A _{\infty} category. This ``derived vector bundle'' must remember the continuity of the original bundle. Concretely, using Floer-Fukaya theory for a monotone (M,Ο‰)(M, \omega) we construct a natural continuous map \begin{equation*} BHam (M, \omega) \to (\mathcal{S}, NFuk (M)), \end{equation*} with (S,NFuk(M))(\mathcal{S}, NFuk (M)) denoting the NFuk(M)NFuk (M) component of the ``space'' of ∞\infty-categories, where NFuk(M)NFuk (M) is the A∞A _{\infty} -nerve of the Fukaya category Fuk(M)Fuk (M). This construction is very closely related to the theory of the Seidel homomorphism and the quantum Chern classes of the author, and this map is intended to be the deepest expression of their underlying geometric theory. In part II the above map is shown to be non trivial by an explicit calculation. In particular we arrive at a new non-trivial ``quantum'' invariant of any smooth manifold and a ``quantum'' Novikov conjecture.Comment: v5, 41 pages.
