The Strict AKNS Hierarchy: Its Structure and Solutions

Abstract EN

We discuss an integrable hierarchy of compatible Lax equations that is obtained by a wider deformation of a commutative algebra in the loop space of s l 2 than that in the AKNS case and whose Lax equations are based on a different decomposition of this loop space.

We show the compatibility of these Lax equations and that they are equivalent to a set of zero curvature relations.

We present a linearization of the system and conclude by giving a wide construction of solutions of this hierarchy.
