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. See more Hadamard-Caccioppoli Theorem If $${\displaystyle U}$$, $${\displaystyle V}$$ are connected open subsets of $${\displaystyle \mathbb {R} ^{n}}$$ such that $${\displaystyle V}$$ is simply connected See more Since any manifold can be locally parametrised, we can consider some explicit maps from $${\displaystyle \mathbb {R} ^{2}}$$ into $${\displaystyle \mathbb {R} ^{2}}$$. • Let See more • Anosov diffeomorphism such as Arnold's cat map • Diffeo anomaly also known as a gravitational anomaly, a type anomaly in quantum mechanics • Diffeology, smooth parameterizations on a set, which makes a diffeological space See more Let $${\displaystyle M}$$ be a differentiable manifold that is second-countable and Hausdorff. 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.
