摘要：
On-shell supergravity vertex operators in an AdS(5) x S-5 background are described in the pure spinor formalism by the zero mode cohomology of a BRST operator. After expanding the pure spinor BRST operator in terms of the AdS(5) radius variable, this cohomology is computed using 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).
