Relativistic fluid spheres with particular application in cosmology and gravitational collapse
Ron Wiltshire
A spherically symmetric comoving fluid solution of Einstein's equations is adapted for cosmological application by extending the geometry of standard FRW cosmology using a generali…

On Linearizing Systems of Diffusion Equations
Christodoulos Sophocleous, Ron J. Wiltshire
We consider systems of diffusion equations that have considerable interest in Soil Science and Mathematical Biology and focus upon the problem of finding those forms of this class…

Slowly rotating, compact fluid sources embedded in Kerr empty space-time
Ron Wiltshire
Spherically symmetric static fluid sources are endowed with rotation and embedded in Kerr empty space-time up to an including quadratic terms in an angular velocity parameter using…
