Prerequisites

This is very much a proof-based course, so the assumption is that you have experience with mathematical proofs and you know how to read and write them. Homework and exam problems all ask you to prove various statements on your own. The main technical prerequisites are

Textbook

We will work mostly based on lecture notes (typed up by a colleague of mine for a previous instance of this course), which I will make available. For additional material I recommend

Homework

We exchange homework via UB Learns: I post the assignments there through the 'Assignments' facility provided by the system and you'll similarly be able to upload files.

Unless specified otherwise, the exercises are from the lecture notes, and numbered identically.

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

treat it as final-exam preparation

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.

Exams

We're having two take-home midterms and one final. The 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.

Grading

We'll drop the two lowest homework scores.
