Assignments:

There will be a mid-term exam (20%), occasional homeworks (20%), one 30 minute presentation by each student (25%), and a final exam (35%).

Resources:

There is no single textbook for the class. Reading will be assigned from the following books on reserve in the library, and other papers will be handed out.
