A survey on the inverse integrating factor
Isaac A. García, Maite Grau
The relation between limit cycles of planar differential systems and the inverse integrating factor was first shown in an article of Giacomini, Llibre and Viano appeared in 1996. F…
Generalized Hopf Bifurcation for planar vector fields via the inverse integrating factor
Isaac A. Garcia, Hector Giacomini, Maite Grau
In this paper we study the maximum number of limit cycles that can bifurcate from a focus singular point of an analytic, autonomous differential system in the real plane unde…
The inverse integrating factor and the Poincaré map
Isaac A. Garcia, Hector Giacomini, Maite Grau
This work is concerned with planar real analytic differential systems with an analytic inverse integrating factor defined in a neighborhood of a regular orbit. We show that the inv…
Integrability and explicit solutions in some Bianchi cosmological dynamical systems
Javier Chavarriga, I. A. García
The Einstein field equations for several cosmological models reduce to polynomial systems of ordinary differential equations. In this paper we shall concentrate our attention to th…
