英文释义

名词 n.
  1. The set of all real, square symmetric matrices whose diagonal entries are all equal to one and whose eigenvalues are all non-negative.
    — In particular, we use a known lower bound on the size of matrix representations of extremal quantum correlations which we apply to high-rank extreme points of the n-dimensional elliptope. Lastly, we study cpsd-graphs, i.e., graphs G with the property that every doubly nonnegative matrix whose support is given by G is cpsd.
