elliptope
Definitions
The set of all real, square symmetric matrices whose diagonal entries are all equal to one and whose eigenvalues are all non-negative.
Examples
“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.”
