  Time      :       December 1 (Wednesday) AM  10:00 - 11:10

  

  Topic     :       Symbolic Dynamics for Non-autonomous Symplectic Twist Maps

                        near the Anti-integrable Limit

　

  Abstract  :

  The anti-integrability theory of Aubry is extended to non-autonomous symplectic

  twist maps to show the shift dynamics can be embedded in a natural way.

  Topic     :      Devil's Staircase Entropy and Dimension in Maps with Horizontal Gap

　

  Abstract  :

  This talk addresses the entropy and dimension (upper, lower and Hausdorff) of a map

   with a horizontal gap. The entropy and dimension of these maps is shown to form a 

   devil's staircase structure with respect to the gap size. Similar Pesin's theorem for

   these maps is also considered.
