After expanding the pure spinor BRST operator in terms of the AdS 5 radius variable, this cohomology is computed using $ \mathcal{N}=4 $ harmonic superspace variables and explicit super-field expressions are obtained for the behavior of supergravity vertex operators near the boundary of AdS 5. © 2013 SISSA, Trieste, Italy.engAdS-CFT CorrespondenceBRST QuantizationSuperspacesArtigo10.1007/JHEP03(2013)022WOS:000317521200022Acesso aberto2-s2.0-848762168142-s2.0-84876216814.pdf
