Invariant solutions and conservation laws of Einstein field equations in non-comoving radiation fields
(Physical Society of the Republic of China, 2021-01-08)
The exact non-static accelerating solutions of Einstein field equations in non-comoving pure radiation fields, corresponding to an indefinite non-degenerate metric in cartesian coordinates, are obtained. The gravitational ...
On new symmetries and exact solutions of Einstein�s field equation for perfect fluid distribution
(Springer, 2021-07-27)
Some new infinite-dimensional generalised Lie symmetries of Einstein�s field equations for perfect fluid distribution are found by using the Lie symmetry analysis. The reduced ordinary differential equations are solved to ...
