Sufficient and Necessary Conditions for Semidefinite Representability of Convex Hulls and Sets
J. William Helton, Jiawang Nie
A set $S\subseteq \re^n$ is called to be {\it Semidefinite (SDP)} representable if equals the projection of a set in higher dimensional space which is describable by some Linea…
