A class of nonlinear wave equations containing the continuous Toda case
E. Alfinito, M. S. Causo, G. Profilo +1
We consider a nonlinear field equation which can be derived from a binomial lattice as a continuous limit. This equation, containing a perturbative friction-like term and a free pa…

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…

The symmetry structure of the heavenly equation
E. Alfinito, G. Soliani, L. Solombrino
We show that excitations of physical interest of the heavenly equation are generated by symmetry operators which yields two reduced equations with different characteristics. One eq…
