Complexity invariance by replication in the quantum square well
Ricardo Lopez-Ruiz, Jaime Sanudo
A new kind of invariance by replication of a statistical measure of complexity is considered. We show that the set of energy eigenstates of the quantum infinite square well display…

The homotopy analysis method and the Lienard equation
Saied Abbasbandy, Jose-Luis Lopez, Ricardo Lopez-Ruiz
In this work, Lienard equations are considered. The limit cycles of these systems are studied by applying the homotopy analysis method. The amplitude and frequency obtained with th…

Bifurcation Curves of Limit Cycles in some Lienard Systems
Ricardo Lopez-Ruiz, Jose-Luis Lopez
Lienard systems of the form , with f(x) an even continous function, are considered. The bifurcation curves of limit cycles are calculated exactly in the…
