From the text: Rotations on $$\mathbb{T}$$ have very simple dynamics. Poincaré asked under which condition a given homeomorphism $$f$$ of $$\mathbb{T}$$ is equivalent (in some sense, e.g.: measurably, topologically, smoothly, analytically, etc.) to some rotation. He also gave a first answer to this question, today known as Poincare’s classification theorem.
