In classical mechanics, a vague torus is a region in phase space that is characterized by approximate constants of motion, as opposed to an actual torus defined by exact constants of motion.The concept of vague tori is used to describe regular (quasiperiodic) segments of otherwise chaotic trajectories. (Wikipedia).

Alba Malaga - Paper Tori - G4G14 Apr 2022
What is a torus? What does it mean for it to be everywhere flat? Can it be realized as a polyhedron in the euclidean space? We discuss these questions and describe a simple universal family of polyhedral flat tori, the diplotori.
