A vectorial Darboux transformation for integrable matrix versions of the Fokas-Lenells equation
Folkert Müller-Hoissen, Rusuo Ye
Using bidifferential calculus, we derive a vectorial binary Darboux transformation for an integrable matrix version of the first negative flow of the Kaup-Newell hierarchy. A reduc…

Miura transformation in bidifferential calculus and a vectorial Darboux transformation for the Fokas-Lenells equation
Folkert Müller-Hoissen, Rusuo Ye
Using a general result of bidifferential calculus and recent results of other authors, a vectorial binary Darboux transformation is derived for the first member of the "negative" p…
