Divergence and Poincare-Liapunov constants for analytic differential systems
MetadataShow full item record
We consider a planar autonomous real analytic differential system with a monodromic singular point p. We deal with the center problem for the singular point p. Our aim is to highlight some relations between the divergence of the system and the Poincaré-Liapunov constants of p when these are defined.

The problem of distinguishing between a center and a focus for nilpotent and degenerate analytic systems Giacomini, Héctor; Giné, Jaume; Llibre, Jaume (Elsevier, 2006)In this work we study the centers of planar analytic vector fields which are limit of linear type centers. It is proved that all the nilpotent centers are limit of linear type centers and consequently the Poincaré–Liapunov ...
