I spent a fair amount of today sitting around in the PMC office thinking about cool problems of CO 380, a very interesting course which I am not enrolled in. Most of the problems are elementary and combinatorial, and admit elegant and rather cute proofs. I will perhaps post about it when the assignment deadline has passed.
Here‘s an interesting paper about methods for evaluating
I am pretty sure we saw the residue calculus technique in PMATH 352 (see here, ; I highly approve of this), and the Fourier analytic technique in PMATH 450.
Also, it seems like I will soon be working with the Waterloo Mathematics Review as an editor!
EDIT: Midterm 1 complete; it was pretty easy. C U @ CUMC.
