We present a procedure to calculate 1/d corrections to the two-particleproperties around the infinite dimensional dynamical mean field limit. Ourmethod is based on a modified version of the scheme of Ref.onlinecite{SchillerIngersent}}. To test our method we study the Hubbard modelat half filling within the fluctuation exchange approximation (FLEX), aselfconsistent generalization of iterative perturbation theory. Apart from theinherent unstabilities of FLEX, our method is stable and results in causalsolutions. We find that 1/d corrections to the local approximation arerelatively small in the Hubbard model.Comment: 4 pages, 4 eps figures, REVTe
