KW - hyperplane arrangement, reducibility, freeness.
AB - <p style="text-align: justify;">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.</p>
