A modified version of the Ishimori model endowed with SU(1,1) symmetry is proposed. Some classes of both rational and biperiodic exact singular solutions are obtained. These solutions are characterized by a topological charge.

A modified version of the Ishimori model endowed with SU(1,1) symmetry is proposed. Some classes of both rational and biperiodic exact singular solutions are obtained. These solutions are characterized by a topological charge.File in questo prodotto:
