Description

Differential equations model systems throughout science and engineering and display rich dynamical behavior. This course empahsizes the qualitative and geometric ideas which characterize the modern (post Poincaré) theory. The course surveys a broad range of topics with emphasis on techniques, and results that are useful in applications.

Outline.

  • Phase line. Dynamics in dimension 1 and 1.5. Bifurcations. Poincar´e map.
  • Existence, uniqueness and perturbations.
  • Theory of linear systems.
  • Linearization at equilibria. Theory of constant coefficient systems. Spectral theorems.
    (The case of multiple eigenvalues and the ergodic properties of coupled oscillators complement introductory treatments).
  • The geometry of phase plane of linear systems..
  • Stable and unstable manifolds.
  • Conjugation of sinks/sources.
  • Lyapunov’s method. LaSalle’s invariance principal.
  • Gradient flows and hamiltonian systems.
  • Periodic solutions, stability, Poincar´e map, !-limit set, Poincaré-Bendixson.
  • Bifurcation theory of equilibria. Pitchfork and Hopf.
  • Introduction to chaotic dynamics. Definitions and first examples.
