Problem Sets
Exercises in bold in the Problem Sets are especially important and typically present some additional insight on the subject. Any changes to problem sets and due dates will be announced in class and on the course web page. Working together is allowed in problem sets. However, you must write up your results individually and indicate the names of your collaborators. Use of existing solutions is not allowed.
