"Introduction to Hadamard matrices and their quantum symmetries"

Continuing last Thursday's talk, we will introduce the Banica-Nicoara quantum symmetry groups of Hadamard matrices. These provide some interesting quantum groups, and in some sense capture some symmetries associated with the matrix.

"Sheaves"

We will be starting next week with the first section on chapter 2 of Algebraic Geometry by Robin Hartshorne. There will be an overview talk on sheaves and then if time permits, tackle some problems on sheaves in Hartshorne.
