Let $\\Delta$ denote the hyperbolic Laplacian which acts on smooth sections of the flat bundle over $M$ associated to $\\chi$. From the spectral theory of $\\Delta$, there are three distinct sequences of numbers: The first coming from the eigenvalues of $L^{2}$ eigenfunctions, the second coming from resonances associated to the continuous spectrum, and the third being the set of negative integers. Using these sequences of spectral data, we employ the super-zeta approach to regularization and introduce two super-zeta functions, $\\Z_-(s,z)$ and $\\Z_+(s,z)$ that encode the spectrum of $\\Delta$ in such a way that they can be used to define the regularized determinant of $\\Delta-z(1-z)I$. The resulting formula for the regularized determinant of $\\Delta-z(1-z)I$ in terms of the Selberg zeta function, see Theorem 5.3, encodes the symmetry $z\\leftrightarrow 1-z$, which could not be seen in previous works, due to a different definition of the regularized determinant.", "revisions": [ { "version": "v1", "updated": "2020-11-23T18:39:44.000Z" } ], "analyses": { "subjects": [ "11M36", "11F72" ], "keywords": [ "regularized determinant", "cofinite fuchsian groups", "finite-dimensional unitary representations", "super-zeta functions", "finite dimensional unitary representation" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
