Topic:

A few $c_2$ invariants of circulant graphs

Description:

The $c_2$ invariant is an arithmetic graph invariant introduced by Brown and Schnetz in order to better understand Feynman integrals. I will look at what can be said about the $c_2$ invariant of 4-regular circulant graphs with one vertex removed. The answer is not much, but it's still interesting. Yes, this is the same talk as I gave at SFU on October 6, so don't come expecting something new.
