Location of the centers of Giant Anticyclons relative to spiral arms, as it depends on the sign of kappa^2 (square of the epicyclic frequency) and on which force is predominant in the gaseous disk: hydrodynamic pressure, self-gravity or external forces
Character of description of the gaseous disk	kappa^2>0	kappa^2<0
Hydrodynamics	In Spiral	Between spiral
Self-gravitation	Between spiral	In Spiral
Boundary of gravitational stability	Between spiral
External non-axially symmetric gravitational potential	Center of vortices may be shifted relative to density exterema	Center of vortices may be shifted relative to density exterema
