Quantum Consistency of the Superstring in AdS_{5} × S^{5} Background
Abstract
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 theory. Cohomology arguments are also used to prove the existence of an infinite set of nonlocal BRSTinvariant charges at the quantum level.
