On higher-derivative dilatonic gravity in two dimensions
We discuss lowering the order of the two-dimensional scalar-tensor R2 quantum gravity, by mapping the most general version of the model to a multi-dilaton gravity, which is essentially the sigma-model coupled with the Jackiw-Teitelboim-like gravity. In the continuation of our previous research, we calculate the divergent part of the one-loop effective action in a 2D scalar-tensor (dilatonic) gr...
متن کاملOn Higher Derivative Gravity In Two Dimensions
The 2D gravity described by the action which is an arbitrary function of the scalar curvature f(R) is considered. The classical vacuum solutions are analyzed. The one-loop renormalizability is studied. For the function f = R lnR the model coupled with scalar (conformal) matter is exactly integrated and is shown to describe a black hole of the 2D dilaton gravity type. The influence of one-loop q...
متن کاملDilatonic gravity near two dimensions as a string theory
Using the renormalization-group formalism, a sigma model of a special type —in which the metric and the dilaton depend explicitly on one of the string coordinates only— is investigated near two dimensions. It is seen that dilatonic gravity coupled to N scalar fields can be expressed in this form, using a string parametrization, and that it possesses the usual UV fixed point. However, in this st...
متن کاملOn the renormalization of higher derivative two dimensional gravity
The fourth derivative models for two dimensional gravity are shown to be equivalent to the special version of the nonlinear sigma models coupled to 2d quantum gravity. The reduction consists in the introduction of the auxiliary scalar fields and can be performed in an explicit way for both metric and general metric-dilaton cases. In view of this we can evaluate the structure of possible counter...
متن کاملQuantum dilatonic gravity in d = 2 , 4 and 5 dimensions
We review (mainly) quantum effects in the theories where gravity sector is described by metric and dilaton. The one-loop effective action for dilatonic gravity in two and four dimensions is evaluated. Renormalization group equations are constructed. The conformal anomaly and induced effective action for 2d and 4d dilaton coupled theories are found. It is applied to study of quantum aspects of b...
