Super Virasoro Algebras From Chiral Supergravity
نویسنده
چکیده
In this note, we construct Noether charges for the chiral supergravity, which contains the Lorentz Chern–Simons term, by applying Wald’s prescription to the vielbein formalism. We investigate the AdS3/CFT2 correspondence by using the vielbein formalism. The asymptotic symmetry group is carefully examined by taking into account the local Lorentz transformation, and we construct super Virasoro algebras with central extensions from the chiral supergravity.

Superspace geometrical realization of theN- extended super Virasoro algebra and its dual
We derive properties of N-extended GR super Virasoro algebras. These include adding central extensions, identification of all primary fields and the action of the adjoint representation on its dual. The final result suggest identification with the spectrum of fields in supergravity theories and superstring/M-theory constructed from NSR N-extended supersymmetric GR Virasoro algebras.

متن کاملN = 2 W-supergravity
We quantise the classical gauge theory of N = 2 w ∞-supergravity and show how the underlying N = 2 super-w ∞ algebra gets deformed into an N = 2 super-W ∞ algebra. Both algebras contain the N = 2 super-Virasoro algebra as a subalgebra. We discuss how one can extract from these results information about quantum N = 2 W N-supergravity theories containing a finite number of higher-spin symmetries ...
متن کاملFractional Superspace Formulation of Generalized Super-Virasoro Algebras
We present a fractional superspace formulation of the centerless parasuper-Virasoro and fractional super-Virasoro algebras. These are two different generalizations of the ordinary super-Virasoro algebra generated by the infinitesimal diffeomorphisms of the superline. We work on the fractional superline parametrized by t and θ, with t a real coordinate and θ a paragrassmann variable of order M a...
متن کاملPhysikalisches Institut A Note on the Algebraic Evaluation of Correlators in Local Chiral Conformal Field Theory
We comment on a program designed for the study of local chiral algebras and their representations in 2D conformal field theory. Based on the algebraic approach described by W. Nahm, this program efficiently calculates arbitrary n-point functions of these algebras. The program is designed such that calculations involving e.g. current algebras, W-algebras and N–Superconformal algebras can be perf...
