| Abstract: | We consider a central hyperplane arrangement in a three-dimensional vector space.The definition of characteristic form to a hyperplane arrangement is given and we could make use of characteristic form to judge the reducibility of this arrangement.In addition,the relationship between the reducibility and freeness of a hyperplane arrangement is given. |
