**Instructor: **Ben McMillan

**Email:** bmcmillan@math.stonybrook.edu

**Locataion:** MW 2:00pm--3:50pm in Library E4330

### Course Information:

The course syllabus is here. Some critical points:
- The midterm will be in class on Monday, March 5.
- My office hours this term are Mondays and Tuesdays 11:30am--12:30pm in the math tower, office 2-116. I will also be available in the MLC (S-235) on Wednesdays 1:00--2:00pm.

### Schedule and Homework:

The following is a tentative schedule for the course. As homework is assigned it will be posted here. You are encouraged to work with others, but please make sure to write up solutions in your own words (this will help you on the exams!).

Unless stated otherwise, the homework is from the corresponding section of the book.

All of the problems assigned in week n are due at the beginning of lecture on the Wednesday of week n+1.
