A diffeomorphism is a concept from differential geometry and calculus, representing a special type of mapping between smooth manifolds. Specifically, a diffeomorphism is a function that meets the following criteria: 1. **Smoothness**: The function is infinitely differentiable (i.e., it is a C^∞ function) and its inverse is also infinitely differentiable.
