**Written Homework: **will be assigned after each lecture. Since
one section of the course is taught on MWF and the other on TuTh
it is not possible to assign the exact same homework after each lecture.
However we will do our best so that the combined sets of all homework problems
that were assigned to the two sections over the whole term are the same. The
graders will be instructed to follow the same rules when grading the homeworks for the two section.

The Written homework and the due dates for Chernov’s section can be found here;

The Written homework and the due dates for Sadykov’s section can be found here;

**Late
homework will not be accepted.** If you feel there is a very legitimate reason for your homework
to be late you should discuss this with the Instructor to your section **in advance**. **Unexcused and missing papers count zero.** **The homework assignment for which the score is the lowest will be
dropped when computing the total grade. **

**Tutorials
**for the class are 7-9 PM
on Tuesdays, Thursdays and Sundays in **Kemeny**** 006.** They
will be run by the Graduate Student Teaching Assistant Avram
Gottschlich. **Please
note that the students in the previous years found these tutorials to be very
helpful!**
