WebA fiber preserving diffeomorphism will be a diffeomorphism ψ : d(V ) × W → V satisfying d(ψ(x, w)) = x, where W is some open subset of an Euclidean space of the appropriate dimension. We now discuss the differentiability condition on a family P = (Px ), a condition which, when satisfied, implies that P f is smooth for all smooth f ∈ Cc ... Since every diffeomorphism is a homeomorphism, given a pair of manifolds which are diffeomorphic to each other they are in particular homeomorphic to each other. The converse is not true in general. While it is easy to find homeomorphisms that are not diffeomorphisms, it is more difficult to find a pair of homeomorphic manifolds that are not diffeomorphic. In dimensions 1, 2 and 3, any pair o…
