Scholar-generated biography
Ke Zhang is a mathematician specializing in dynamical systems, with a focus on Hamiltonian systems, Weak KAM theory, and Arnold diffusion. His research explores the long-term behavior of mechanical systems, particularly in the context of chaotic dynamics and diffusion phenomena. Zhang's work includes the study of normally hyperbolic invariant cylinders, the speed of Arnold diffusion, and the thermodynamics of hyperbolic systems. He has also investigated the Birkhoff conjecture and the stability of quasi-convex systems. His contributions span both theoretical and applied aspects of dynamical systems, with an emphasis on analytical and geometric methods.
