Lie symmetry approach to the time-dependent Karmarkar condition
Andronikos Paliathanasis, Robert S. Bogadi, Megandhren Govender
We obtain solutions of the time-dependent Einstein Field Equations which satisfy the Karmarkar condition via the method of Lie symmetries. Spherically symmetric spacetime metrics a…

Stability and Horizon Formation during Dissipative Collapse
Nolene F. Naidu, Robert S. Bogadi, Anand Kaisavelu +1
We investigate the role played by density inhomogeneities and dissipation on the final outcome of collapse of a self-gravitating sphere. By imposing a perturbative scheme on the th…
