The nonlocal Darboux transformation of the stationary axially symmetric Schrödinger equation and generalized Moutard transformation
Andrey Kudryavtsev
The nonlocal Darboux transformation of the stationary axially symmetric Schrödinger equation is considered. It is shown that a special case of the nonlocal Darboux transformation p…
