Query: Fixed points, bounded orbits and attractors of planar flows   In this paper we provide a dynamical characterization of isolated invariant
continua which are global attractors for planar dissipative flows. As a
consequence, a sufficient condition for an isolated invariant continuum to be
either an attractor or a repeller is derived for general planar flows.
