我们建立了相关多面体的扩张复杂性至少是通过一个简短的证明,该证明是自包含的,除了使用多面体的每个面都是它所包含的所有面的交集这一事实。证明的主要创新点是一个简单的组合论证,证明了唯一不相交矩阵的矩形覆盖数至少为,因此唯一不相交谓词的不确定通信复杂度至少为.因此,我们对以前最著名的下界和分别略有改进。
We establish that the extension complexity of thecorrelation polytope is at leastby a short proof that is self-contained except for using the fact that every face of a polyhedron is the intersection of all facets it is contained in. The main innovative aspect of the proof is a simple combinatorial argument showing that the rectangle covering number of the unique-disjointness matrix is at least, and thus the nondeterministic communication complexity of the unique-disjointness predicate is at least. We thereby slightly improve on the previously best known lower boundsand, respectively.
