The diffeomorphism group of $${\displaystyle M}$$ is the group of all Topology See more 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 … See more
