Starting from the large-N power counting which suggests that the baryons are QCD solitons, the authors derive an exact large-N equation identical to the so-called bootstrap condition of static strong-coupling theory. This equation determines the group structure of the baryon multiplets at N. One solution is the standard nonrelativistic quark model.
