For a finite abstract simplicial complex, we can look at the Dirac Zeta function, the Connection Zeta function and the Lefschetz zeta function. My work on this in the last couple of years

- An elementary Dyadic Riemann Hypothesis (2018)
- Brouwer fixed point theorem for graph endomorphisms (2012) (journal link)
