Hawking radiation as tunneling for extremal and rotating black holes
The issue concerning semi-classical methods recently developed in deriving the conditions for Hawking radiation as tunneling, is revisited and applied also to rotating black hole solutions as well asExpand

Local Hawking temperature for dynamical black holes
A local Hawking temperature is derived for any future outer trapping horizon in spherical symmetry, using a Hamilton?Jacobi variant of the Parikh?Wilczek tunneling method. It is given by a dynamicalExpand

Black holes with unusual topology
Einstein's equations with a negative cosmological constant admit solutions which are asymptotically anti\char21{}de Sitter space. Matter fields in anti\char21{}de Sitter space can be in stableExpand

Zeta-Function Regularization, the Multiplicative Anomaly and the Wodzicki Residue
Abstract:The multiplicative anomaly associated with the zeta-function regularized determinant is computed for the Laplace-type operators V1=−Δ+V1 and V2=−Δ+V2, with V1, V2 constant, in aExpand

Quantum fields and extended objects in space-times with constant curvature spatial section
Abstract The heat-kernel expansion and ζ-regularization techniques for quantum field theory and extended objects on curved space-times are reviewed. In particular, ultrastatic space-times withExpand

Quantum properties of topological black holes
We examine quantum properties of topological black holes which are asymptotically anti--de Sitter. First, massless scalar fields and Weyl spinors which propagate in the background of an anti--deExpand

Tunnelling methods and Hawking's radiation: achievements and prospects
The aim of this work is to review the tunnelling method as an alternative description of the quantum radiation from black holes and cosmological horizons. The method is first formulated and discussedExpand

Aspects of quantum gravity in de Sitter spaces
In this paper we give a review of recent attempts to understand quantum gravity on de Sitter spaces. In particular, we discuss the holographic correspondence between de Sitter gravity and conformalExpand
