On approximations of the PSD cone by a polynomial number of smaller-sized PSD cones
Abstract We study the problem of approximating the cone of positive semidefinite (PSD) matrices with a cone that can be described by smaller-sized PSD constraints. Specifically, we ask the question: “how closely can we approximate the set of unit-trace...
