Abstract: We construct the gravitational energy-momentum pseudo-tensor of up to fourth-order conformally invariant theories of gravity. Then we linearize the pseudo-tensor and use its average over a macroscopic region to find the energy and momentum carried by the plane gravitational waves of the three main conformally invariant theories of gravity.
According to the article, the authors have constructed the gravitational energy-momentum pseudo-tensor for conformally invariant theories of gravity up to fourth order. They further linearized the pseudo-tensor and calculated the average energy and momentum carried by plane gravitational waves in three main conformally invariant theories of gravity.
Conclusion
The conclusions of this research indicate progress in understanding the energy and momentum properties of conformally invariant theories of gravity. By constructing the gravitational energy-momentum pseudo-tensor and calculating its averages, the authors have made significant contributions to the field.
