Kam tori are invariant tori in Hamiltonian dynamical systems that arise from KAM (Kolmogorov-Arnold-Moser) theory, which describes the persistence of quasi-periodic orbits under small perturbations. These tori are significant because they represent stable, regular motion in systems that might otherwise exhibit chaotic behavior. Understanding kam tori helps in analyzing the long-term behavior of celestial mechanics, as they illustrate how certain orbits can survive even when the system is slightly altered.
congrats on reading the definition of kam tori. now let's actually learn it.
