AI总结:
针对对称锥上的余正锥,本文通过构造非暴露极射线,证明维数不小于2时其不具有面暴露性,推广了非负正交情形的已知结论。
摘要:
本文考虑对称锥上的余正锥,并证明当底层锥的维数至少为2时,它们绝不是面暴露的。我们通过显式给出一条非暴露极射线来做到这一点。我们的结果推广了已知事实,即非负正交补上的余正矩阵锥通常不是面暴露的。
英文摘要:
In this paper, we consider copositive cones over symmetric cones and show that they are never facially exposed when the underlying cone has dimension at least 2. We do so by explicitly exhibiting a non-exposed extreme ray. Our result extends the known fact that the cone of copositive matrices over the nonnegative orthant is not facially exposed in general.
