The flow is generated by the gravitationally dressed thermal operator Φ_{1,3} coupled to the renormalized loop tension λ~ T-T_c. We find that the susceptibility as a function of the thermal coupling λand the cosmological constant μsatisfies a simple transcendental equation.14 pages, 2 figures; contribution to QTS-4, Varna, BulgariaHigh Energy Physics - Theorytext
