RT Journal Article T1 The Darboux system: finite-rank constraints and Darbouxtransformations A1 Guil Guerrero, Francisco A1 Mañas Baena, Manuel AB The exponential solutions of the Darboux equations for conjugate nets is considered. It is shown that rank-one constraints over the right derivatives of invertible operators on an arbitrary linear space give solutions of the Darboux system, which can be understood as a vectorial Darboux transformation of the exponential background. The method is extended further to obtain vectorial Darboux transformations of the Darboux system.
