Renormalization for critical orders close to 2N
Judith Cruz, Daniel Smania
We study the dynamics of the renormalization operator acting on the space of pairs (v,t), where v is a diffeomorphism and t belongs to [0,1], interpreted as unimodal maps x-->v(q_t…
Integrable models, degenerate horizons and AdS_2 black holes
J. Cruz, A. Fabbri, D. J. Navarro +2
The near extremal Reissner-Nordstrom black holes in arbitrary dimensions ca be modeled by the Jackiw-Teitelboim (JT) theory. The asymptotic Virasoro symmetry of the corresponding J…
Integrable models and degenerate horizons in two-dimensional gravity
J. Cruz, A. Fabbri, D. J. Navarro +1
We analyse an integrable model of two-dimensional gravity which can be reduced to a pair of Liouville fields in conformal gauge. Its general solution represents a pair of ``mirror'…
On the normalization of Killing vectors and energy conservation in two-dimensional gravity
J. Cruz, A. Fabbri, J. Navarro-Salas
We explicitly show that, in the context of a recently proposed 2D dilaton gravity theory, energy conservation requires the ``natural'' Killing vector to have, asymptotically, an un…
Can conformal Transformations change the fate of 2D black holes?
J. Cruz, A. Fabbri, J. Navarro-Salas
By using a classical Liouville-type model of two dimensional dilaton gravity we show that the one-loop theory implies that the fate of a black hole depends on the conformal frame.…
Free Fields for Chiral 2D Dilaton Gravity
J. Cruz, J. Navarro-Salas, M. Navarro
We give an explicit canonical transformation which transforms a generic chiral 2D dilaton gravity model into a free field theory.
