Multi-dimensional Virasoro algebra and quantum gravity
نویسنده
چکیده
I review the multi-dimensional generalizations of the Virasoro algebra, i.e. the non-central Lie algebra extensions of the algebra vect(N) of general vector fields in N dimensions, and its Fock representations. Being the Noether symmetry of background independent theories such as N -dimensional general relativity, this algebra is expected to be relevant to the quantization of gravity. To this end, more complicated modules which depend on dynamics in the form of Euler-Lagrange equations are described. These modules can apparently only be interpreted as quantum fields if spacetime has four dimensions and both bosons and fermions are present.

Loop Equations and Virasoro Constraints in Non-perturbative 2-D Quantum Gravity
We give a derivation of the loop equation for two-dimensional gravity from the KdV equations and the string equation of the one matrix model. We find that the loop equation is equivalent to an infinite set of linear constraints on the square root of the partition function satisfying the Virasoro algebra. We give an interpretation of these equations in topological gravity and discuss their exten...
متن کاملManifestly Covariant Canonical Quantization of Gravity and Diffeomorphism Anomalies in Four Dimensions
Canonical quantization of gravity requires knowledge about the representation theory of its constraint algebra, which is physically equivalent to the algebra of arbitrary 4-diffeomorphisms. All interesting lowest-energy representations are projective, making the relevant algebra into a four-dimensional generalization of the Virasoro algebra. Such diffeomorphism anomalies are invisible in field ...
متن کاملQuantum Jet Theory, Observer Dependence, and Multi-dimensional Virasoro algebra
We review some key features of Quantum Jet Theory: observer dependence, multi-dimensional Virasoro algebra, and the prediction that spacetime has four dimensions.
متن کاملChiral Liouville Gravity
Classical two-dimensional Liouville gravity is often considered in conformal gauge which has a residual left and right Virasoro symmetry algebra. We consider an alternate, chiral, gauge which has a residual right Virasoro Kac-Moody algebra, and no left Virasoro algebra. The Kac-Moody zero mode is the left-moving energy. Dirac brackets of the constrained Hamiltonian theory are derived, and the r...
متن کاملEmbeddings of the Virasoro algebra and black hole entropy
Three-dimensional gravity was put forward by Deser, Jackiw and ’t Hooft [1] as an interesting toy model for gravitational physics. It was then argued in [2] (see also [3]) that it defines a soluble and finite quantum field theory. Questions such as what are the microscopical degrees of freedom giving rise to the Bekenstein-Hawking entropy in three dimensions should then have an answer. However,...
