Abstract

Let Z(s) be the Selberg zeta-function associated to a compact Riemann surface. We consider decompositions Z(s) = f(h(s)), where f and h are meromorphic functions, and show that such decompositions can only be trivial.

Highlights

  • We continue the investigation of decompositions of the Selberg zeta-function which was started in Garunkstis and Steuding [6]

  • The Selberg zeta-function Z associated with a compact Riemann surface of genus g is pseudo-prime and right-prime

  • The Selberg zeta-function Z associated with a compact Riemann surface of genus g ≥ 2 is prime

Summary

Introduction

We continue the investigation of decompositions of the Selberg zeta-function which was started in Garunkstis and Steuding [6]. Defines the Selberg zeta-function in the half-plane σ > 1. The Selberg zeta-function Z associated with a compact Riemann surface of genus g is pseudo-prime and right-prime.
