Abstract
The reduced wave equation with a variable wave speed and its parabolic approximation is considered. For each equation, a Darboux transformation is constructed. For the reduced wave equation, a Darboux transformation is obtained linking solutions to Laplace´s equation. For the parabolic approximation equation, a transformation is obtained linking solutions to Schrodinger´s equation. It is shown that these transformations exist for the same class of variable wave speed.
