  2. GOAL • Find models and parametrize dynamical behaviors. • Describe each model or behavior.

  3. Multimodal maps on the circle G(x) mod 1 G(x+1) = G(x) +d d=2

  4. Multimodal maps on the circle G a lift of a continuous map g on 3 • 2m – modal • degree d • type 2 G 1 • periodic extrema are attractors; • no wandering intervals; • no intervals of periodic points; • periodic attractors are essential. 0 -1 1 0 m = 4, d = 2 G mod 1
