1. chaos generated by 1-dimensional mapping
reductionism and deterministic dynamical system, countable set and uncountable set, periodic orbit and non-periodic orbit, dense orbit.
2. invariant sets generated by 1-dimensional mapping
rigid rotation and quasi-periodic orbit, compact invariant set,Cantor set and similarity dimension.
3. chaotic invariant sets
fixed point theorem and asymptotically stability, tangent mapping and stability of fixed point, stable and unstable manifolds, definition of chaotic invariant sets.
4. attractors
attractor and trapping region, Lyapunov spectrum, horseshoe map and hyperbolic invariant set, Henon map
Lozi map and generalized hyperbolicity.
5. nonlinear phenomena generated by ordinary differential equation
electrical and kinetic dynamical systems, attractors generated by vector space, Poincare map and difference dynamical systems.
6. local bifurcations
diversity of fixed points, saddle-node bifurcation, period doubling.
7. global bifurcation
