| Abstract: | This paper studies mathematical definition of central configurations in N-body problem.There are two definitions for central configurations,literal definition and mathematical definition.Are the two definitions equivalent? Central configurations in planar regular polygon is taken as an example to analyze differences between literal and mathematical definitions.More reasonable mathematical definition for N-body central configurations is given. |
