A family of non-autonomous hybrid Lienard oscillators based on a parametrically extended commutative factorization
J. de la Cruz, H. C. Rosu, G. Gonzalez +1
We introduce a class of nonautonomous nonlinear oscillator equations of mixed Liénard type that arises from a parametric deformation of the commutative factorization procedure appl…
Solutions of an extended Duffing-van der Pol equation with variable coefficients
O. Cornejo-Pérez, P. Albares, J. Negro
In this work, exact solutions of the nonlinear cubic-quintic Duffing-van der Pol oscillator with variable coefficients are obtained. Two approaches have been applied, one based on…
Isochronous waveforms of Liénard equations via commutative factorization
G. Gonzalez, O. Cornejo-Perez, J. de la Cruz +1
Isochronous waveform solutions of homogeneous Liénard equations are obtained by a modification of the nonlinear factorization method of Rosu and Cornejo-Pérez. The scheme is based…
New asymptotic techniques for the partial wave cut-off method for calculating the QED one loop effective action
Adolfo Huet, Idrish Huet, Octavio Cornejo
The Gel'fand-Yaglom theorem has been used to calculate the one-loop effective action in quantum field theory by means of the "partial-wave-cutoff method". This method works well fo…
Extension of a factorization method of nonlinear second order ODE's with variable coefficients
H. C. Rosu, O. Cornejo-Perez, M. Perez-Maldonado +1
The factorization of nonlinear second-order differential equations proposed by Rosu and Cornejo-Perez in 2005 is extended to equations containing quadratic and cubic forms in the f…
Nonsingular parametric oscillators Darboux-related to the classical harmonic oscillator
H. C. Rosu, O. Cornejo-Perez, P. Chen
Interesting nonsingular parametric oscillators which are Darboux related to the classical harmonic oscillator and have periodic dissipative/gain features are identified through a m…
