On the Darboux Transformation. I

gmj, 1995
Abstract Automorphisms of the family of all Sturm-Liouville equations y″ = qy are investigated. The classical Darboux transformation arises as a particular case of a general result.

Dressing methodvs. classical Darboux transformation

Il Nuovo Cimento B Series 11, 1984
In this paper we recall some of the essential properties of the classical Darboux transformation and establish its equivalence with the dressing method. In this way we can elucidate and co-ordinate different notions existing in the literature, like Darboux matrix, Darboux transformation and Backlund transformation, which, although being different, are ...

Commutation and Darboux transformation

Pramana, 2015
In this paper we show that the Darboux transformation for a large class of nonlinear evolution equations arises due to factorization and commutation. The factorization and commutation has been pointed out earlier for Schrodinger operator. We show that it extends to a large class of nonlinear differential equations which admit Lax pairs including ...

On multidimensional Darboux transformations

Inverse Problems, 1998
Summary: In contrast to known results on one-dimensional Darboux transformations, results on multidimensional Darboux transformations do not seem convenient for disentangling the sets of solutions in global inverse problems. In the present paper, first, we give a broad generalization of vectorial Darboux transformations and a more limited ...
