The listings below provide a synopsis of the material covered by the TAs in their weekly sessions throughout the course. These listings are not binding and can be changed by the staff at its discretion and without any special notice to the student body. Until a session is actually given, its plan is tentative. There is no binding obligation on the part of the staff that the session would fit its pre-published plan. We also specify the source of the topics covered throughout these sessions If your TA did not cover some of the material in the listing published for a given session, then it is your obligation to study all parts which your TA did not cover on your own according to the source associated with the topic. ​All material produced by the course TAs did not undergo the scrutiny reserved for formal publications. Whenever a source is listed for a topic it is the version seen in that source that dominates in case of conflicts.
