Cylindrical Gravitational Wave: Source and Resonance
2021
Symmetry
Preserved Fulltext
The first kind of singularity corresponds to a singular source. The second kind of singularity corresponds to a resonance between different gravitational waves. ...
When two gravitational waves coexist, the interference term in the source may vanish in the sense of time averaging. ...
Two gravitational waves with sources and two gravitational waves without sources do not resonate with one another. ...

In this paper, we present an exact general solution of the cylindrical gravitational wave. The exact solution of the cylindrical gravitational wave is far different from the weak field approximation. ...
This solution implies the following conclusions. (1) There exist gravitational monopole radiations in the cylindrical gravitational radiation. (2) The gravitational radiation may generate the resonance ...

Solutions analogous to the Weber-Wheeler cylindrical pulse waves are found for the case of cylindrical gravitational waves in an expanding universe. ...
These pulse solutions mimic the asymptotic properties of waves from an isolated source in three dimensions and can be used to test the far-field behavior of numerical simulation techniques. ...
The waves are cylindrical, which accounts for spreading in two dimensions. ...
