SEMINARIO DE FISICA TEORICA I Y II Titulo: Hypotheses for a Lax pair describing `Coalgebra- Integrable' Systems Conferenciante: Orlando Ragnisco ( Universita' de Roma3, Italia ) Dia y hora: 19, 14:15 (aula 8A ) Resumen: Coalgebra integrable systems have been introduced at the end of the previous century, both in the `classical' and in the q- deformed case. Surprisingly enough, these systems seemed not to be amenable (at least in a simple way) to a Lax pair formulation. However quite recently partial results have been obtained that can pave the way for this representation.
