Heating up branes in gauged supergravity
In this note, we explore the solution space of non-extremal black objects in
and gauged supergravity in the presence of fluxes. We
present first order rewritings of the action for a classes of non-extremal
dyonic and electric solutions with electric flux backgrounds. Additionally, we
obtain the non-extremal version of the Nernst brane in using a simple
deformation. Finally, we develop a new technique to deform extremal black
solutions in to non-extremal solutions by an analysis of the symmetries of
the equations of motion.Comment: Minor typographic correction
Attractive holographic c -functions
Using the attractor mechanism for extremal solutions in N = 2 gauged supergravity,
we construct a c-function that interpolates between the central charges of theories
at ultraviolet and infrared conformal fixed points corresponding to anti-de Sitter geometries.
The c-function we obtain is couched purely in terms of bulk quantities and connects
two different dimensional CFTs at the stable conformal fixed points under the RG flow
