Title: Zeta Functions of the Dirac Operator on Quantum Graphs

Abstract: The spectral zeta function generalizes the Riemann zeta function by replacing the sum over integers with a sum over a spectrum. Here we consider the spectrum of the Dirac operator acting on a metric graph. Since all eigenvalues are roots of a secular equation, we can calculate the spectral zeta function by applying the argument principle to a particular contour integral. This will be done first for a rose graph, and then for general graphs with self-adjoint vertex matching conditions. We will also discuss how this function can then be used to compute the spectral determinant.

Based on joint work with J. M. Harrison and K. Kirsten, arXiv:1606.07834.
