Accurate and powerful computational methods developped by the author, based on the analytic resolution of the wave equation in the black hole background, allow to obtain the highly non trivial total absorption spectrum of the Black Hole. As well as phase shifts and cross sections (elastic and inelastic) for a wide range of energy and angular momentum, the angular distribution of absorbed and sc...

In this paper we investigate a dilaton-gravity theory, which can be viewed as an SL(2) conformal affine Toda (CAT) theory. This new model is inspired by some previous work by Bilal, Callan, and de Alwis. The main results obtained in our approach are (i) a field redefinition of the CAT basis in terms of which it is possible to get the black hole solutions already known in the literature, and (ii...

The black hole information paradox suggests that the process by which an object collapses into a black hole and then evaporates by emitting Hawking radiation may destroy information. Further, there seems to be no unique prediction on where the information about the collapsing body is localized. We argue that the latter aspect of the paradox is a manifestation of an inconsistent self-reference i...

The bending analysis of moderately thick elliptic plates weakened by an eccentric circular hole has been investigated in this article. The nonlinear governing equations have been presented by considering the von-Karman assumptions and the first-order shear deformation theory in cylindrical coordinates system. Semi-analytical polynomial method (SAPM) which had been presented by the author before...
