Noether-Charge Realization of Diffeomorphism Algebra
It is shown in the covariant phase space formalism that the Noether charges with respect to the diffeomorphism generated by vector fields and their horizontal variations in general relativity form a diffeomorphism algebra. It is also shown with the help of the null tetrad which is well defined everywhere that the central term of the reduced diffeomorphism algebra on the Killing horizon for a la...
متن کاملThe diffeomorphism algebra approach to quantum gravity
The representation theory of non-centrally extended Lie algebras of Noether symmetries, including spacetime diffeomorphisms and reparametrizations of the observer’s trajectory, has recently been developped. It naturally solves some long-standing problems in quantum gravity, e.g. the role of diffeomorphisms and the causal structure, but some new questions also arise.
متن کاملGauged Nonlinear Sigma Model and Boundary Diffeomorphism Algebra
We consider Chern-Simons gauged nonlinear sigma model with boundary which has a manifest bulk diffeomorphism invariance. We find that the Gauss’s law can be solved explicitly when the nonlinear sigma model is defined on the Hermitian symmetric space, and the original bulk theory completely reduces to a boundary nonlinear sigma model with the target space of Hermitian symmetric space. We also st...
متن کاملOn the Superselection Theory of the Weyl Algebra for Diffeomorphism Invariant Quantum Gauge Theories
Much of the work in loop quantum gravity and quantum geometry rests on a mathematically rigorous integration theory on spaces of distributional connections. Most notably, a diffeomorphism invariant representation of the algebra of basic observables of the theory, the Ashtekar-Lewandowski representation, has been constructed. This representation is singled out by its mathematical elegance, and u...
متن کاملAlgebraic structure of Lorentz and diffeomorphism anomalies
The Wess-Zumino consistency conditions for Lorentz and diffeomorphism anomalies are discussed by introducing an operator δ which allows to decompose the exterior space-time derivative as a BRS commutator. Supported in part by the ”Fonds zur Förderung der Wissenschaftlichen Forschung”, M008-Lise Meitner Fellowship.
