Finite temperature resolution of the Klebanov–Tseytlin singularity Original Research Article

Naked singularities in the gravitational backgrounds dual to gauge theories can be hidden behind the black hole horizon. We present an exact black hole solution in the Klebanov–Tseytlin geometry [I.R. Klebanov, A.A. Tseytlin, hep-th/0002159]. Our solution realizes Maldacena dual of the finite temperature N=1 duality cascade of [I.R. Klebanov, M.J. Strassler, hep-th/0007191] above the temperature of the chiral symmetry breaking. We compare the Bekenstein–Hawking entropy of the black hole with the entropy of the SU(N+M)×SU(N) gauge theory.
