Supersymmetry of FRW barotropic cosmologies
H. C. Rosu, P. Ojeda-May
Barotropic FRW cosmologies are presented from the standpoint of nonrelativistic supersymmetry. First, we reduce the barotropic FRW system of differential equations to simple harmon…
Mathematical methods of factorization and a feedback approach for biological systems
O. Cornejo-Perez
The first part of the thesis is devoted to factorizations of linear and nonlinear differential equations leading to solutions of the kink type. The second part contains a study of…
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…
Robust estimation of the exponent function in the Gompertz law
V. Ibarra-Junquera, M. P. Monsivais, H. C. Rosu +1
The estimation of the solution of a system of two differential equations introduced by Norton (1976) that is equivalent to the Gompertz law is performed by means of the recent adap…
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…
Cyclotomic quantum clock
H. C. Rosu, M. Planat
In the wake of our recent work on cyclotomic effects in quantum phase locking [M. Planat and H. C. Rosu, Phys. Lett. A 315, 1 (2003)], we briefly discuss here a cyclotomic extensio…
