Conservation laws for certain time fractional nonlinear systems of partial differential equations
(Elsevier B.V., 2017)In this study, an extension of the concept of nonlinear self-adjointness and Noether operators is proposed for calculating conserved vectors of the time fractional nonlinear systems of partial differential equations. In ... -
Invariant solutions of Einstein field equations in pure radiation fields
(Springer, 2021-03-06)The exact static accelerating solutions of Einstein�s equations in the non-comoving pure radiation fields, with an indefinite non-degenerate stationary metric in cylindrical coordinates, are obtained. The considered ...
