New exact solutions of Bianchi I, Bianchi III and Kantowski-Sachs spacetimes in scalar-coupled gravity theories via Noether gauge symmetries
U. Camci, A. Yildirim, I. Basaran Oz
The Noether symmetry approach is useful tool to restrict the arbitrariness in a gravity theory when the equations of motion are underdetermined due to the high number of functions…

Dirac Analysis and Integrability of Geodesic Equations for Cylindrically Symmetric Spacetimes
Ugur Camci
Dirac's constraint analysis and the symplectic structure of geodesic equations are obtained for the general cylindrically symmetric stationary spacetime. For this metric, using the…

Matter collineations of Spacetime Homogeneous Gödel-type Metrics
U. Camci, M. Sharif
The spacetime homogeneous Gödel-type spacetimes which have four classes of metrics are studied according to their matter collineations. The obtained results are compared with Killi…
