摘要: 首先, 给出广义平凡位置构形的定义, 并研究平凡位置构形、 广义平凡位置构形、 通有构形之间的关系. 其次, 通过建立构形和简单图的关系, 给出通有阈构形的子构形线性无关的充要条件以及通有阈构形的子构形的特征多项式.

关键词: 通有构形, 平凡位置, 通有阈构形, 特征多项式

Abstract: Firstly, we gave the definition of the generalized general position arrangement, and studied the relationships among the general position arrangements, generalized general position arrangements and generic arrangements. Secondly, by establishing the relationships between arrangements and the simple graphs, we gave the necessary and sufficient   condition for linear independence of the subarrangements of generic threshold arrangements and the characteristic polynomials of the subarrangements of generic threshold arrangements.

Key words: generic arrangement, general position, generic threshold arrangement, characteristic polynomial
