Showing papers on "AdS/CFT correspondence published in 1972"

TL;DR: In this article, the convergence of perturbation theory is established and a comparison is made between the exact energies and their Pade approximations for two simple field theories, both of zero-space dimension, the Riemann surface of the energy as a function of the square of the coupling constant is studied.

TL;DR: In this article, the validity of the kinking theorem is investigated for non-polynomial field theories for which the fields are only functions of time and the usual contour integral methods are shown to be unnecessarily ambiguous.
