The Student Complex Analysis and Dynamical Systems Seminar, Meets Friday, 10:30am – 12:30pm, Room: 4419, coordinated by Yunping Jiang, Linda Keen, and Fred Gardiner

 

If you have any suggestion and question, please email to Professor Jiang at

In the fall semester of 2009, we are interested in complex manifold structures of Teichmuller spaces T(E) of closed sets E and quasiconformal mapping theory and applications to complex dynamical systems like combinatorial characterization of rational maps and entire functions.  The seminar will start on Sept 11th. Prof. Jiang will give the first few lectures and distribute a list of general references in the Sept 11th seminar. Students in the seminar will read these papers and report in the seminar either in this semester or in the next semester.
