Kay's characteristic-data singularity conjecture. The solution determined by these characteristic data will have a singular $T_{vv}$ on the same half-horizon; the analogous stateme…

Kay's silver-plated almost-singularity conjecture. Similar silver-plated stress-energy almost-singularity results will hold in these spacetimes; in particular, there will still be…

Kay's finite-energy singularity conjecture. Quite generally, under these compactness assumptions, there will be classical solutions with finite re-signed Schwarzschild energy, its…

Kay's enclosed-horizon instability conjecture. In other situations with analogous enclosed horizons, including these Schwarzschild and Schwarzschild–AdS examples, there will be sim…
