GBDT version of the Darboux transformation for the matrix coupled dispersionless equations (local and non-local cases)

摘要

We introduce matrix coupled (local and non-local) dispersionless equations, construct GBDT (generalized B?cklund-Darboux transformation) for these equations, derive wide classes of explicit multipole solutions, give explicit expressions for the corresponding Darboux and wave matrix valued functions and study their asymptotics in some interesting cases. We consider the scalar cases of coupled, complex coupled and non-local dispersionless equations as well.
