Fusion Friday talk by Jacob Bridgeman
On Friday April 16, Jacob Bridgeman from the Perimeter Institute gave an expository talk on transfer matrices, the 2D classical Ising model, and the 1D transverse-field Ising model. We will watch this talk during class on Friday 2021/04/30.

Colloquium by Theo Johnson-Freyd
On Thursday April 1, Theo Johnson-Freyd from Dalhousie U/Perimeter Institute will give a colloquium at OSU on the classification of topological orders. As Thursday April 1 falls during the instructional break, we will not hold class on Friday April 2. That way, if you cannot (or do not want to) attend on April 1, you should watch the recording of the colloquium during the class period on Friday April 2.
