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…

Debye-potential generation conjecture. All real solutions of the linearized Einstein vacuum equations on a vacuum type II background can be locally obtained, up to gauge, as the re…

Let $P_L$ be the linearization, at a Riemannian Kottler metric with negative cosmological constant, of the $TT$-gauge-fixed Einstein operator. Here $K$ is the constant sectional cu…
