Riccati nonhermiticity with application to the Morse potential
O. Cornejo-Perez, R. Lopez-Sandoval, H. C. Rosu
A supersymmetric one-dimensional matrix procedure similar to relationships of the same type between Dirac and Schrodinger equations in particle physics is described at the general…

Factorization of damped wave equations with cubic nonlinearities
H C Rosu, O. Cornejo-Perez
The recent factorization scheme that we introduced for nonlinear polynomial ODEs in math-ph/0401040 is applied to the interesting case of damped wave equations with cubic nonlinear…
