👉 A diffeomorphism is a mathematical concept in differential geometry and topology. It is a one-to-one correspondence between smooth manifolds (manifolds with continuous differentiable structures) that preserves the topological structure of the space. In other words, it maps tangent vectors to tangent vectors, and its inverse is also a diffeomorphism. Diffeomorphisms are essential in many areas of mathematics, physics, engineering, and computer science. They allow us to analyze manifolds
