I'll probably ask you to read some of the sections in the textbook before most lectures, so we're in sync. I'll post the reading assignments here. Unless specified otherwise the sections are those in Rotman's book.

The date is that of the lecture, so please do the reading before that.

1 Th, Jan 30 Sections 1.1 and 1.2
2 Th, Feb 6 For the homework due that day you'll maybe want to remind yourself of

Supplementary material

Starting the week of Mar 23, all course materials will appear below.

All assignments are due Thursday in class, as indicated in the table below.

Because of the ad-hoc online nature of the class, starting after Spring break please email the homework as an attachment, directly to uploads.5u0zr1zpby8bb5fg "at"

No late homework for any reason, but we are dropping the two lowest scores.

The grader will assign each homework a grade out of 10 with only a few problems being graded (3 or 4 or so). There will also be points awarded for the overall completeness of the assignment. I won't be telling you in advance which problems are being graded though..

Do collaborate on the homework if you like, but write up your own solutions. I also strongly advise you to have a look at the UB Academic Integrity Policy, as it very much applies to this class.

And by all means drop by at office hours if you need a hand.

We're having two take-home exams. The due dates are as follows

Exam policy:

Those are the due dates. I will post the problem lists a few days before, so you will have plenty of time to work on them.
We'll drop the two lowest homework scores.
If you have any questions, don't hesitate to email me.
