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.

Curvature collineations in certain gravitational space-times
General Relativity and Gravitation, 1975 It has been shown that the space-times formed from the product of two surfaces and from a thick gravitational plane wave sandwiched between two flat spacetimes admit proper curvature collineation in general. The curvature collineation vectors have been determined explicitly.

Perfect fluid spacetimes admitting curvature collineations
General Relativity and Gravitation, 1991 This paper discusses curvature collineations in perfect fluid spacetimes within Einstein's general relativity. Using as starting point the papers of the reviewer [Gen. Relativ. Gravitation 15, 581-589 (1983; Zbl 0514.53018)] and the reviewer are and the second author [J. Math. Phys. 32, No.

Proper curvature collineations in Bianchi type-II space-times
Il Nuovo Cimento B, 2006 The author studies Bianchi type I space-times according to their proper curvature collineations (CCs). These curvature collineations are vector fields along which the Lie derivative of the Riemann tensor is zero. An approach is adopted connected with using the rank of the \(6\times6\) Riemann matrix, direct integration techniques, and also the theorem ...
