Einstein and Yang-Mills theories in hyperbolic form without gauge fixing.

چکیده
The evolution of physical and gauge degrees of freedom in the Einstein and Yang-Mills theories are separated in a gauge-invariant manner. We show that the equations of motion of these theories can always be written in fluxconservative first-order symmetric hyperbolic form. This dynamical form is ideal for global analysis, analytic approximation methods such as gaugeinvariant perturbation theory, and numerical solution.

Unconstrained Hamiltonian Formulation of SU(2) Gluodynamics
One of the main issues in the Hamiltonian formulation of Yang-Mills theories is to find the projection from the phase space of canonical variables constrained by the non-Abelian Gauss law to the “smaller” phase space of unconstrained gauge invariant coordinates only. Dealing with the problem of the elimination of the pure gauge degrees of freedom two approaches exist, the perturbative and the n...
متن کاملM ay 1 99 8 Existence theorems for hairy black holes in su ( N ) Einstein - Yang - Mills theories
We establish the existence of hairy black holes in su(N) Einstein-Yang-Mills theories, described by N − 1 parameters, corresponding to the nodes of the gauge field functions.
متن کاملGauge fixing and BRST formalism in non-Abelian gauge theories
In this Thesis we present a comprehensive study of perturbative and non-perturbative non-Abelian gauge theories in the light of gauge-fixing procedures, focusing our attention on the BRST formalism in Yang-Mills theory. We propose first a model to re-write the Faddeev-Popov quantisation method in terms of grouptheoretical techniques and then we give a possible way to solve the no-go theorem of ...
متن کاملYang-Mills/Einstein/Tensor Supergravity: Abelian Case
We give a detailed study of the critical points of the potentials of the simplest non-trivial N = 2 gauged Yang-Mills/Einstein supergravity theories with tensor multiplets. The scalar field target space of these examples is SO(1, 1)×SO(2, 1)/SO(2). The possible gauge groups are SO(2)×U(1)R and SO(1, 1) × U(1)R, where U(1)R is a subgroup of the R-symmetry group SU(2)R, and SO(2) and SO(1, 1) are...
متن کاملGauge Fixing and Renormalization in Topological Quantum Field Theory*
In this letter we show how Witten’s topological Yang-Mills and gravitational quantum field theories may be obtained by a straightforward BRST gauge fixing procedure. We investigate some aspects of the renormalization of the topological Yang-Mills theory. It is found that the beta function for the Yang-Mills coupling constant is not zero. Submitted to Phys. Lett. * Work supported by the Departme...
