0 Hamiltonian structure and gauge symmetries of Poincaré gauge theory ∗
This is a review of the constrained dynamical structure of Poincaré gauge theory which concentrates on the basic canonical and gauge properties of the theory, including the identification of constraints, gauge symmetries and conservation laws. As an interesting example of the general approach we discuss the teleparallel formulation of general relativity.
متن کاملPoincaré gauge theory of (2+1)-dimensional gravity.
A Poincaré gauge theory of (2+1)-dimensional gravity is developed. Fundamental gravitational field variables are dreibein fields and Lorentz gauge potentials, and the theory is underlain with the Riemann-Cartan space-time. The most general gravitational Lagrangian density, which is at most quadratic in curvature and torsion tensors and invariant under local Lorentz transformations and under gen...
متن کاملTowards complete integrability of two-dimensional Poincaré gauge gravity.
It is shown that gravity on the line can be described by the two dimensional (2D) Hilbert–Einstein Lagrangian supplemented by a kinetic term for the coframe and a translational boundary term. The resulting model is equivalent to a Yang–Mills theory of local translations and frozen Lorentz gauge degrees. We will show that this restricted Poincaré gauge model in 2 dimensions is completely integra...
متن کاملTwisted K-theory and Poincaré duality
Using methods of KK-theory, we generalize Poincaré K-duality to the framework of twisted K-theory.
