WebMar 24, 2024 · A diffeomorphism is a map between manifolds which is differentiable and has a differentiable inverse. See also Anosov Diffeomorphism, Axiom A … In mathematics, a diffeomorphism is an isomorphism of smooth manifolds. It is an invertible function that maps one differentiable manifold to another such that both the function and its inverse are differentiable.
