Noether Symmetry Analysis of the Klein--Gordon and Wave Equations in Bianchi I Spacetime
Ugur Camci
We investigate the Noether symmetries of the Klein--Gordon Lagrangian for Bianchi I spacetime. This is accomplished using a set of new Noether symmetry relations for the Klein--Gor…
Conformal symmetries of the energy-momentum tensor of spherically symmetric static spacetimes
Ugur Camci, Khalid Saifullah
Conformal matter collineations of the energy-momentum tensor for a general spherically symmetric static spacetime are studied. The general form of these collineations is found when…
Integration of the geodesic equations via Noether Symmetries
Ugur Camci
Through this article, I will overview the use of Noether symmetry approach in discussing the integration of geodesic equations for the geodesic Lagrangians of spacetimes. I will al…
On Dark Matter As A Geometric Effect in the Galactic Halo
Ugur Camci
We obtain more straightforwardly some features of dark matter distribution in the halos of galaxies by considering the spherically symmetric space-time, which satisfies the flat ro…
Three-dimensional black holes via Noether symmetries
Ugur Camci
We investigate the Noether symmetries of the Lagrangian for the stationary rotating BTZ-type three-dimensional spacetimes in theory of gravity. A detailed analysis of Noethe…
