Remarks on certain separability structures and their applications to general relativity
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 vacuumExpand

Extended theories of gravity and their cosmological and astrophysical applications
Astrophysical observations are pointing out huge amounts of “dark matter” and “dark energy” needed to explain the observed large scale structure and cosmic dynamics. The emerging picture is aExpand

Variational formulation of general relativity from 1915 to 1925 “Palatini's method” discovered by Einstein in 1925
Among the three basic variational approaches to general relativity, the metric-affine variational principle, according to which the metric and the affine connection are varied independently, isExpand

A Geometrie Perspective on Irreversible Thermodynamics with Internal Variables
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
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 ofExpand
