Summary: Let \(M\) be a Riemann surface of constant curvature \(-1\), finite geometry and totally geodesic compact boundary. With a similar definition to the Selberg’s zeta function associated to a Riemann surface of finite area, the zeta function \(Z_ M\) is expressed through spectral invariants (eigenvalues and resonances) and extends so to a meromorphic function on the entire complex plane. Linked to trace formulas of Selberg’s and Birman-Krejn’s type, the proof is based on the meromorphic extensions of the resolvent of various Laplacians and the following (stationary and non-stationary) scattering theory.
For the entire collection see [Zbl 0771.00036].
