Short survey of Darboux transformations
H. C. Rosu
A selective chronological survey of Darboux transformations as related to supersymmetric quantum mechanics, intertwining operators and inverse scattering techniques is presented. S…

Strictly isospectral SUSY potentials and the Riccati superposition principle
H. C. Rosu
The connection of unbroken SUSY quantum mechanics in its strictly isospectral form with the nonlinear Riccati superposition principle is pointed out

q deformation by intertwining with application to the singular oscillator
H. C. Rosu, C. Castro
We present a version of q-deformed calculus based on deformed counterparts of Darboux intertwining operators. The case in which the deformed transformation function is of the vacuu…
