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…
One-parameter isospectral special functions
M. A. Reyes, D. Jimenez, H. C. Rosu
Using a combination of the ladder operators of Pina [Rev. Mex. Fis. 41 (1995) 913] and the parametric operators of Mielnik [J. Math. Phys. 25 (1984) 3387] we introduce second order…
Second-order linear differential equations associated to a Riccati equation of constant coefficients
H. C. Rosu, O. Cornejo, M. Reyes +1
We present several second-order linear differential equations that are associated to a particular Riccati equation with only one constant parameter in its coefficients through the…
Milne phase for the Coulomb quantum problem related to Riemann's hypothesis
H. C. Rosu, J. M. Moran-Mirabal, M. Planat
We use the Milne phase function in the continuum part of the spectrum of the particular Coulomb problem that has been employed by Bhaduri, Khare, and Law as an equivalent physical…
Differential equations extended to superspace
J. Torres, H. C. Rosu
We present a simple SUSY N=2 superspace extension of the differential equations in which the sought solutions are considered to be real superfields but maintaining the common deriv…
