On higher-derivative dilatonic gravity in two dimensions
S. Naftulin, S. D. Odintsov
We discuss lowering the order of the two-dimensional scalar-tensor quantum gravity, by mapping the most general version of the model to a multi-dilaton gravity, which is esse…
On Black Holes in the Theory of Dilatonic Gravity Coupled to a Scalar Field
E. Elizalde, P. Fosalba-Vela, S. Naftulin +1
Taking advantage of the representation of dilatonic gravity with the -term under the form of low-derivative dilatonic gravity coupled to an additional scalar, we construct a g…
Quantum reparametrizations in the two-dimensional gravity: a look from 2+ dimensions
S. Naftulin
We discuss the structure of one-loop counterterms for the two-dimensional theory of gravitation in the covariant scheme and study the effect of quantum reparametrizations. Some of…
One-Loop Renormalization of Higher-Derivative 2D Dilaton Gravity
E. Elizalde, S. Naftulin, S. D. Odintsov
A theory of higher-derivative 2D dilaton gravity which has its roots in the massive higher-spin mode dynamics of string theory is suggested. The divergences of the effective action…
The Renormalization Structure and Quantum Equivalence of 2D Dilaton Gravities
E. Elizalde, S. Naftulin, S. D. Odintsov
The one-loop effective action corresponding the general model of dilaton gravity given by the Lagrangian $L=-\sqrt{g} \left[ \frac{1}{2}Z(Φ) g^{μν} \partial_μΦ\partial_νΦ+ C(Φ) R +…
2D Dilaton-Maxwell Gravity as a Fixed Point of the Renormalization Group
E. Elizalde, S. Naftulin, S. D. Odintsov
A general model of dialton-Maxwell gravity in two dimensions is investigated. The corresponding one-loop effective action and the generalized -functions are obtained. A set of m…
