BRST cohomology and nonlocal conserved charges
(2005-02-01)
A relation is found between nonlocal conserved charges in string theory and certain ghost-number two states in the BRST cohomology. This provides a simple proof that the nonlocal conserved charges for the superstring in ...

Quantum consistency of the superstring
(2005-03-01)
Using arguments based on BRST cohomology, the pure spinor formalism for the superstring in an AdS 5×S 5 background is proven to be BRST invariant and conformally invariant at the quantum level to all orders in perturbation ...
A Note on Scalar Field Theory in AdS3/CFT2
(World Scientific, 2010-06)
We consider a scalar field theory in AdSd+1, and introduce a formalism on surfaces at equal values of the radial coordinate. In particular, we define the corresponding conjugate momentum. We compute the Noether currents ...
