Generalized 2d dilaton gravity with matter fields
نویسندگان
چکیده
We extend the classical integrability of the CGHS model of 2d gravity [1] to a larger class of models, allowing the gravitational part of the action to depend more generally on the dilaton field and, simultaneously, adding fermion– and U(1)–gauge–fields to the scalar matter. On the other hand we provide the complete solution of the most general dilaton–dependent 2d gravity action coupled to chiral fermions. The latter analysis is generalized to a chiral fermion multiplet with a non–abelian gauge symmetry as well as to the (anti–)self–dual sector df = ± ∗ df of a scalar field f . e-mail: [email protected] e-mail: [email protected]

Symmetries in Two-dimensional Dilaton Gravity with Matter
The symmetries of generic 2D dilaton models of gravity with (and without) matter are studied in some detail. It is shown that δ2, one of the symmetries of the matterless models, can be generalized to the case where matter fields of any kind are present. The general (classical) solution for some of these models, in particular those coupled to chiral matter, which generalizes the Vaidya solution ...

We discuss the relationship between two-dimensional (2D) dilaton gravity models and sine-Gordon-like field theories. We show that there is a one-to-one correspondence between the solutions of 2D dilaton gravity and the solutions of a (two fields) generalization of the sine-Gordon model. In particular, we find a connection between the soliton solutions of the generalized sine-Gordon model and ex...
متن کاملGeometric interpretation and classification of global solutions in generalized dilaton gravity.
Two dimensional gravity with torsion is proved to be equivalent to special types of generalized 2d dilaton gravity. E.g. in one version, the dilaton field is shown to be expressible by the extra scalar curvature, constructed for an independent Lorentz connection corresponding to a nontrivial torsion. Elimination of that dilaton field yields an equivalent torsionless theory, nonpolynomial in cur...

We show that an anomaly-free description of matter in (1+1) dimensions requires a correction of the 2d relativity principle, which is connected to a noncommutativity of 2d Minkowski space that introduces a 2d Planck length. Then, in order to dynamically describe this noncommutative structure of the tangent space, we propose to extend the usual 2d generalized dilaton gravity models by a non-stan...
متن کاملExact Path Integral Quantization of Generic 2-D Dilaton Gravity
Local path integral quantization of generic 2D dilaton gravity is considered. Locality means that we assume asymptotic fall off conditions for all fields. We demonstrate that in the absence of ‘matter’ fields to all orders of perturbation theory and for all 2D dilaton theories the quantum effective action coincides with the classical one. This resolves the apparent contradiction between the wel...
