AdS black holes and thermal Yang-Mills correlators
read the original abstract
We study the real time correlators of scalar glueball operators for Yang-Mills theory at finite temperature in flat space. The analytic structure of the frequency space propagator in perturbative field theory is seen to be qualitatively different to the strong coupling results that may be obtained from perturbations about AdS black hole spacetimes: we find branch cuts rather than poles. This difference appears to persist away from the strict zero and infinite coupling limits, possibly suggesting a phase transition in large N thermal N = 4 SYM theory as a function of the 't Hooft coupling.

$O(d,d)$ 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.

$O(d,d)$ 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.
