Abstract:
In the preceding paper(hep-th/9806084), we constructed submodels of nonlinear Grassmann sigma models in any dimension and, moreover, an infinite number of conserved currents and a wide class of exact solutions. In this paper, we first construct almost all conserved currents for the submodels and all ones for the one of CP1{\bf C}P^1-model. We next review the Smirnov and Sobolev construction for the equations of CP1{\bf C}P^1-submodel and extend the equations, the S-S construction and conserved currents to the higher order ones.
