On the absence of conformally flat slicings of the Kerr spacetime

Antonio de Felice, François Larrouturou, Shinji Mukohyama +1

This work investigates the possibility of achieving a conformally flat slicing of the Kerr spacetime. We consider a hypersurface of the form $t=F(r,\theta ,a)$, where $(t,r,\theta ,\varphi )$ are t…
