Title: Counting the $c_2$ invariant on the circulant family of graphs

Speaker: Mushegh Shahinyan
Affiliation: University of Waterloo
Zoom: Contact Karen Yeats

Abstract:

The algebro-geometric invariant on Feynman Diagrams called the $c_2$ invariant is a useful tool for detecting properties of Feynman periods. We present this identity on graphs that originate from the scalar $\phi_4$-theory with a purely combinatorial perspective and go over some strategies for computing it. We will further narrow our focus onto the circulant family of graphs and present some explicit results.
