Algebraic properties of the 1+1 dimensional Heisenberg spin field model
E. Alfinito, M. Leo, R. A. Leo +2
The Estabrook-Wahlquist prolongation method is applied to the (compact and noncompact) continuous isotropic Heisenberg model in 1 + 1 dimensions. Using a special realization (an al…

Integrable nonlinear field equations and loop algebra structures
E. Alfinito, M. Leo, R. A. Leo +2
We apply the (direct and inverse) prolongation method to a couple of nonlinear Schr{ö}dinger equations. These are taken as a laboratory field model for analyzing the existence of a…
