We study central configurations lying on a common circle in the Newtonian four-body problem. Using topological argument we prove that there is at most one co-circular configuration for each cyclic ordering of masses circle.

Uniqueness Results for Co-Circular Central Configurations for Power-Law Potentials
For a class of potential functions including those used for the planar n-body and n-vortex problems, we investigate co-circular central configurations whose center of mass coincides with the center of the circle containing the bodies. Useful equations are derived that completely describe the problem. Using a topological approach, it is shown that for any choice of positive masses (or circulatio...
متن کاملClassification of four-body central configurations with three equal masses
It is known that a central configuration of the planar four body problem consisting of three particles of equal mass possesses a symmetry if the configuration is convex or is concave with the unequal mass in the interior. We use analytic methods to show that besides the family of equilateral triangle configurations, there are exactly one family of concave and one family of convex central config...
متن کاملConvex Four Body Central Configurations with Some Equal Masses
We prove that there is a unique convex non-collinear central configuration of the planar Newtonian four-body problem when two equal masses are located at opposite vertices of a quadrilateral and, at most, only one of the remaining masses is larger than the equal masses. Such central configuration posses a symmetry line and it is a kite shaped quadrilateral. We also show that there is exactly on...
متن کاملOn the central configurations of the planar restricted four-body problem
This article is devoted to answering several questions about the central configurations of the planar (3 + 1)-body problem. Firstly, we study bifurcations of central configurations, proving the uniqueness of convex central configurations up to symmetry. Secondly, we settle the finiteness problem in the case of two nonzero equal masses. Lastly, we provide all the possibilities for the number of ...
متن کاملFlat Central Configurations of Four Planet Motions
Abst rac t . The flat central configurations of four planet motions are investigated with ~¥u's elimination method. ~¥e obtain 12 collinear central configurations and a necessary condition for determining flat but noncollinear central configurations. We also prove that the number of central configurations in planet motions of 4 bodies is finite under the condition that the masses and angular ve...
