Cylindrical Gravitational Wave: Source and Resonance [PDF]
Symmetry, 2021 Gravitational waves are regarded as linear waves in the weak field approximation, which ignores the spacetime singularity. In this paper, we analyze singularities in exact gravitational wave solutions. We provide an exact general solution of the gravitational wave with cylindrical symmetry.
