Proper curvature collineations in non-static plane symmetric space-times

open access: yes, 2010
The most general form of non-static plane symmetric space-times is considered to study proper curvature collineations by using the rank of the 6X6 Riemann matrix and direct integration techniques. Studying proper curvature collineations in each non static case of the above space-times it is shown that when the above space-times admit proper curvature ...

Curvature‐driven Multi‐stream Network for Feature‐preserving Mesh Denoising

open access: yes
Mesh denoising is a fundamental yet challenging task. Most of the existing data‐driven methods only consider the zero‐order information (vertex location) and first‐order information (face normal).

IMPOSING CURVATURE RESTRICTIONS ON A TRANSLOG COST FUNCTION USING A MARKOV CHAIN MONTE CARLO SIMULATION APPROACH [PDF]

open access: yes
Using Kansas Farm data from 1973 to 1998, curvature restrictions are imposed on a translog cost function. Using uninformative priors with indicator functions representing distribution and inequality constraints, a Markov Chain Monte Carlo Simulation ...

Study of curvature collineations in anisotropic cosmologies: Bianchi type-III and Kantowski-Sachs models in f(R, T) gravity

open access: yes
In this paper, anisotropic Bianchi type-III spatial homogeneity and Kantowski-Sachs cosmological model have been explored in the presence of the $f\!\left (R,T\right )$ theory.

Symmetries and curvature structure in general relativity

open access: yes, 2004
This book is a text on classical general relativity from a geometrical viewpoint. Introductory chapters are provided on algebra, topology and manifold theory together with a chapter on the basic ideas of space-time manifolds and Einstein's theory.
