New shear-free relativistic models with heat flow
A. M. Msomi, K. S. Govinder, S. D. Maharaj
We study shear-free spherically symmetric relativistic models with heat flow. Our analysis is based on Lie's theory of extended groups applied to the governing field equations. In…

Noether and Lie symmetries for charged perfect fluids
M. C. Kweyama, K. S. Govinder, S. D. Maharaj
We study the underlying nonlinear partial differential equation that governs the behaviour of spherically symmetric charged fluids in general relativity. We investigate the conditi…
