In even dimension $D=2m$, consider conformal gravity actions whose Euler–Lagrange equations admit every Einstein metric as a solution. Uniqueness conjecture. There is only one such…

Let $d4d4_g$ and $d4d4$ denote the linearized conformal-gravity and general-relativity theories, respectively, and let $d4d0\mathrm{bs}^{\mathrm{cl}}(-,d4d4)$ denote their classica…

A four-dimensional background is Bach-flat when its Bach tensor vanishes, and a partially massless field is a linear partially massless spin-2 field propagating on that background.…
