The Brown - Henneaux ’ s central charge from the path - integral boundary condition
نویسنده
چکیده
We derive the Brown-Henneaux’s commutation relation and central charge in the framework of the path integral. If we use the leading part of the asymptotic symmetry to derive the Ward-Takahashi identity, we can see the central charge arises from the fact that the boundary condition of the path integral is not invariant under the transformation.

Path integral derivation of the Brown - Henneaux central charge
We rederive the Brown-Henneaux commutation relation and central charge in the framework of the path integral. To obtain the WardTakahashi identity, we can use either the asymptotic symmetry or its leading part. If we use the asymptotic symmetry, the central charge arises from the transformation law of the charge itself. Thus, this central charge is clearly different from the quantum anomaly whi...

متن کاملConsistent Boundary Conditions for New Massive Gravity in AdS 3
In this note we study the boundary conditions for the new massive gravity theory in asymptotically AdS3 spacetime. We find that the Brown-Henneaux boundary conditions are consistent with the new massive gravity for all any value of the mass parameter. At the critical point where the central charge vanishes, the conserved charges vanish, too. This confirms that the theory is trivial at the criti...

متن کاملString Theory on AdS 3
It was shown by Brown and Henneaux that the classical theory of gravity on AdS3 has an infinite-dimensional symmetry group forming a Virasoro algebra. More recently, Giveon, Kutasov and Seiberg (GKS) constructed the corresponding Virasoro generators in the first-quantized string theory onAdS3. In this paper, we explore various aspects of string theory on AdS3 and study the relation between thes...
