## Categorification of the Ihara Zeta Function

##### Abstract:

Zeta functions are central objects of study in number theory, and can often be found wherever there is Galois theory. In this talk, we will discuss the Ihara zeta function of an undirected graph and compare it to the Dedekind zeta function. Then we will talk about incidence algebras and use them to describe a categorification of both types of zeta functions.
