Remark on the variational principle in the AdS/CFT correspondence for the scalar field
arXiv:hep-th/9910233 · doi:10.1016/S0370-2693(99)01361-1
Abstract
We discuss how the variational principle can be used as a criterion for choosing, among scalar field actions implying the same equation of motion, the appropriate one for the AdS/CFT correspondence.
