Abstract

We study the Center Problem for equations v' = Σi=1ai(x)vi+1. This problem is closely connected to the classical Poincaré Center-Focus problem about the characterization of planar polynomial vector fields whose integral trajectories are closed curves with interiors containing a fixed point, a center.
