| Abstract: | In this paper, an equivalent definition is given for the central configuration in the classical n body problem in terms of certain linear systems, and then it is used as a criterion to determine whether certain confiqurations are central. This yields a unified simple approach to certain known results and gives some new results.$$$$ |
