Abstract
In this paper, Einstein–Maxwell equations for non-static cylindrical symmetric metric are investigated to find Lie’s infinitesimal symmetries. The new conservation theorem with nonlinear self-adjointness and direct method of multipliers are utilized to obtain the conservation laws. The system of Einstein–Maxwell equations has also been proved to be nonlinear self-adjoint by using criterion given by Ibragimov.
