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…
Noether symmetries of the minimal surface Lagrangian for Gödel-type spacetimes
Ugur Camci
We investigate the Noether symmetries of the minimal surface Lagrangian for four classes of metrics in Gödel-type spacetimes. Then, calculating the Noether symmetries for all class…
Physical Significance of Noether Symmetries
Asghar Qadir, Ugur Camci
In this paper we will trace the development of the use of symmetry in discussing the theory of motion initiated by Emmy Noether in 1918. Though it started with its use in Classical…
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…
