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…

Semidefinite Representation of Convex Sets
J. William Helton, Jiawang Nie
Let $S =\{x\in \re^n: g_1(x)\geq 0, ..., g_m(x)\geq 0\}$ be a semialgebraic set defined by multivariate polynomials . Assume is convex, compact and has nonempty interio…
