Zeta-function on the generalised cone
Guido Cognola, Sergio Zerbini
The analytic properties of the zeta-function for a Laplace operator on a generalised cone are studied in some detail using the Cheeger's approach and explicit expressions are given…
Determinant of Laplacian on a non-compact 3-dimensional hyperbolic manifold with finite volume
A. A. Bytsenko, Guido Cognola, Sergio Zerbini
The functional determinant of Laplace-type operators on the 3-dimensional non-compact hyperbolic manifold with invariant fundamental domain of finite volume is computed by quadratu…
Quantum Fields in Hyperbolic Space-Times with Finite Spatial Volume
A. A. Bytsenko, Guido Cognola, Sergio Zerbini
The one-loop effective action for a massive self-interacting scalar field is investigated in -dimensional ultrastatic space-time , being a non-compact h…
Euclidean Approach to the Entropy for a Scalar Field in Rindler-like Space-Times
Sergio Zerbini, Guido Cognola, Luciano Vanzo
The off-shell entropy for a massless scalar field in a D-dimensional Rindler-like space-time is investigated within the conical Euclidean approach in the manifold $C_\be\times\M^N$…
