Kostyukova O. I., Tchemisova T.

摘要:

本文研究了共正矩阵的锥$\cop$.基于已知的半无限优化概念的不动指标,我们定义了锥$\cop$的一个子集的零和最小零向量,并利用它们得到了$\cop$的面和相应的对偶锥的不同表示.我们描述的最小面的$\cop$包含一个给定的凸子集,这个锥,并证明了一些命题,允许获得等价的描述的可行集的一个共正问题,并可能是有用的创建新的数值方法的基础上,他们的正规化。

英文摘要:

The paper is devoted to a study of the cone $\cop$ of copositive matrices. Based on the known from semi-infinite optimization concept of immobile indices, we define zero and minimal zero vectors of a subset of the cone $\cop$ and use them to obtain different representations of faces of $\cop$ and the corresponding dual cones. We describe the minimal face of $\cop$ containing a given convex subset of this cone and prove some propositions that allow to obtain equivalent descriptions of the feasible sets of a copositive problems and may be useful for creating new numerical methods based on their regularization.
