    "abstract": "We apply the (direct and inverse) prolongation method to a couple of\nnonlinear Schr{\\\"o}dinger equations. These are taken as a laboratory field\nmodel for analyzing the existence of a connection between the integrability\nproperty and loop algebras. Exploiting a realization of the Kac-Moody type of\nthe incomplete prolongation algebra associated with the system under\nconsideration, we develop a procedure with allows us to generate a new class of\nintegrable nonlinear field equations containing the original ones as a special\ncase.",
