Curvature Singularities: the Good, the Bad, and the Naked
read the original abstract
Necessary conditions are proposed for the admissibility of singular classical solutions with 3+1-dimensional Poincare invariance to five-dimensional gravity coupled to scalars. Finite temperature considerations and examples from AdS/CFT support the conjecture that the scalar potential must remain bounded above for a solution to be physical. Having imposed some restrictions on naked singularities allows us to comment on a recent proposal for solving the cosmological constant problem.

Sharpened Dynamical Cobordism
Sharpened Dynamical Cobordism ties the allowed range of critical exponent δ to theory structure ξ, flagging obstructions from non-trivial cobordism charges that require new degrees of freedom.

The phase diagram of confining holographic theories on constant curvature manifolds in the presence of a $\theta$-angle
Holographic confining QFTs on negative-curvature manifolds show no phase transitions with a dominant saddle, while positive-curvature cases exhibit first- and second-order transitions depending on the theory class, pl...

$O(d,d)$ symmetric gravity and finite coupling holography
In O(d,d) symmetric gravity with curvature corrections, black brane singularities persist with altered Kasner exponents, while dilaton effects enable dynamic generation of negative cosmological constants at weak coupling.

Scattering off Chamblin-Reall Branes
Holographic analysis of scattering off Chamblin-Reall branes shows that for d>1 incident radiation redistributes into reflected, transmitted, and evanescent components, with d=2 yielding diffuse scattering like a tran...

$O(d,d)$ symmetric gravity and finite coupling holography
In O(d,d) symmetric gravity with curvature corrections, black brane singularities are not resolved but approach with altered Kasner exponents, while a dilaton generates negative cosmological constants at small coupling.
