Investigations of Selberg Zeta Functions Under Character Deformations

  • Markus Szymon Fraczek
Part of the Lecture Notes in Mathematics book series (LNM, volume 2139)


In this chapter we present the numerical results we obtained using our computer program package Morpheus for the transfer operators \(\mathcal{L}_{\beta,\varepsilon,\chi }^{\left (n\right )}\) in Sect.  7.6 and the Selberg zeta function \(Z^{\left (n\right )}(\beta,\chi )\) for \(\varGamma _{0}\left (n\right )\) and character χ given by
$$\displaystyle{Z^{\left (n\right )}(\beta,\chi ) =\det \left (1 -\tilde{\mathcal{L}}_{\beta,\chi }^{\left (n\right )}\right ) =\det \left (1 -\mathcal{L}_{\beta,+1,\chi }^{\left (n\right )}\mathcal{L}_{\beta,-1,\chi }^{\left (n\right )}\right ) =\det \left (1 -\mathcal{L}_{\beta,-1,\chi }^{\left (n\right )}\mathcal{L}_{\beta,+1,\chi }^{\left (n\right )}\right ).}$$
