Remarks on certain separability structures and their applications to general relativity

- S. Benenti, M. Francaviglia
- Physics
- 1979

General results of the theory of separability for the geodesic equation in (Vn, g) are applied to deduce the canonical form of a separable metric withn- 2 Killing vectors. Applications to vacuum… Expand

A Geometrie Perspective on Irreversible Thermodynamics with Internal Variables

- M. Dolfin, M. Francaviglia, P. Rogolino
- Physics
- 1 October 1998

The thermodynamics of simple materials is analysed from a geometrical point of view. The model provides a suitable framework for dissipative structures arising during the evolution of the system.

Anti-Kählerian manifolds

- A. Borowiec, M. Francaviglia, I. Volovich
- Mathematics
- 1 May 2000

Abstract An anti-Kahlerian manifold is a complex manifold with an anti-Hermitian metric and a parallel almost complex structure. It is shown that a metric on such a manifold must be the real part of… Expand
