报告摘要

The double copy is currently a highly researched prescription for connecting (non-)abelian gauge theory solutions with gravitational counterparts. In this talk, I will briefly review two types of classical double copies---Kerr-Schild double copy and Weyl double copy. A new method for verifying the Weyl double copy relation for non-twisting vacuum Petrov type N and vacuum Petrov type D solutions will be presented. The case of type III solutions will also be discussed. Based on this methodology, I will extend the research to vacuum spacetimes with a cosmological constant and show that the zeroth and single copies satisfy conformally invariant field equations in conformally flat spacetime. In particular, I will demonstrate how the zeroth copy is critical in radiation solution.
