Description
The 1/N expansion of the effective action of the O(N) model is formulated as a loop expansion. Three variations of the expansion are given: one which requires the fewest graphs for a given order, one in which the power of 1/N coincides with the number of loops, and one which does not involve mixed propagators and which is easily applied to the study of the complete effective action
