چکیده
We write the field equations of torsion gravity theories and Noether identity they obey directly in terms metric contorsion tensor components expressed with respect to natural coordinates, i.e., without using vierbien but Lagrange multipliers. Then we obtain explicit solutions these equations, under specific ans\"atze for field, by assuming be respectively Bertotti-Robinson, pp-wave, Friedmann-Lema\^{\i}tre-Robertson-Walker or static spherically symmetric type. Among various some them have their depending on arbitrary functions that did not influence geometry. This raises questions about predictability theory.

Einstein-Cartan-Heisenberg Theory of Gravity with Dynamical Torsion
On the basis of an algebraic relation between torsion and a classical spinor field a new interpretation of Einstein-Cartan gravity interacting with a classical spinor field is proposed. In this approach the spinor field becomes an auxiliary field and the dynamical equation for this field (the Heisenberg equation) is a dynamical, gravitational equation for torsion. The simplest version of this t...
متن کاملLinearized Gravity in Brane Backgrounds
Abstract A treatment of linearized gravity is given in the Randall-Sundrum background. The graviton propagator is found in terms of the scalar propagator, for which an explicit integral expression is provided. This reduces to the four-dimensional propagator at long distances along the brane, and provides estimates of subleading corrections. Asymptotics of the propagator off the brane yields exp...
متن کاملTorsion formulation of gravity
We make it precise what it means to have a connection with torsion as solution of the Einstein equations. While locally the theory remains the same, the new formulation allows for topologies that would have been excluded in the standard formulation of gravity. In this formulation it is possible to couple arbitrary torsion to gauge fields without breaking the gauge invariance.
متن کاملEuclidean 2D Gravity with Torsion
Closing a gap in the literature on the subject, the local solutions of 2D-gravity with torsion are given for Euclidean signature. For the topology of a cylinder the system is quantized in a Dirac approach.
متن کاملExact Solutions, Symmetries and Quantization of Two-dimensional Higher-derivative Gravity with Dynamical Torsion
We investigate two-dimensional higher derivative gravitational theories in a Riemann-Cartan framework. We obtain the most general static black hole solutions in conformal coordinates and discuss their geometry. We also consider the hamiltonian formulation of the theory and discuss its symmetries, showing that it can be considered as a gauge theory of a non-linear generalizations of the 2-dimens...
