First, a mathematical model of quasiperiodic Hamiltonian systems is introduced. Then, using the Poincaré-Birkhoff theorem, it is proved that these systems exhibit topological non-equivariance, i.e., the phase space of the system cannot be identified by continuous and equivariant mappings. Next, the stability of equilibrium points of these systems is analyzed and studied using linearization and center manifold theorem. Finally, some specific examples and numerical simulations are given to verify the theoretical results.Keywords:quasiperiodic Hamiltonian systems; mathematical model; Poincaré-Birkhoff theorem; linearization method; center manifold theorem; stability of equilibrium points.
