Projective Motion, Projective Curvature Collineation and Infinitesimal Projective Transformation in a Finsler Space Equipped with Semi-Symmetric Connection

The present communication has been devoted to the study of projective motion, projective curvature collineation and infinitesimal projective transformation in a Finsler space equipped with semi-symmetric connection. In this communication we have derived results in the form of theorems which hold when the Finsler space under consideration admits both ...

Collineations of the curvature tensor in general relativity

Pramana - Journal of Physics, 2005
Curvature collineations for the curvature tensor, constructed from a fundamental Bianchi Type-V metric, are studied. We are concerned with a symmetry property of space-time which is called curvature collineation, and we briefly discuss the physical and kinematical properties of the models.

A note on curvature collineations in spacetimes

Classical and Quantum Gravity, 2005
Summary: An example of a spacetime is given in which the Lie algebra of curvature collineations, although finite-dimensional, is distinct from the affine algebra.

Curvature collineations in general relativity. II

Journal of Mathematical Physics, 1991
This paper is the second of a set of two papers on curvature collineations in general relativity. The first paper presented the mathematical basis of curvature collineations and a possible approach to their study. This paper continues from the first one by investigating in detail many of the cases where curvature collineations can occur in space-time ...

Curvature collineations in conformally flat spacetimes

Classical and Quantum Gravity, 2001
Summary: A study of curvature collineations in conformally flat spacetimes is given. It is shown that the only possibilities are (special cases of the) FRW metrics (and their spacelike equivalents), the Bertotti-Robinson metrics and null fluid metrics.
