Binary Darboux transformations and \(N\)-wave systems in rings
This paper deals with the covariance theorems for elementary and binary Darboux transformations in rings. The author extends the definition of the elementary Darboux transformation to an arbitrary number of orthogonal idempotents and proves a covariance theorem for the generalized Zacharov-Shabat (ZS) problems. The author gives examples that generalize the \(N\)-wave system viewed as a zero-curvature condition for the appropriate pair of ZS problems.
