We survey what is known, offer many explicit examples and some proofs, and give applications to CR geometry. We prove one new algebraic theorem: a non-negative Hermitian symmetric polynomial divides a nonzero squared norm if and only if it is a …

Webthe distillability problem is deeply related to the 2-decomposable map in operator algebra, the generalized Cauchy inequality conjecture, and Hilbert’s 17th problem [12]. Although there have been some attempts to the distillability problem [13{16], the complete solution is unknown. The main di culty is that it involves rapidly increasing ...

Hilbert's seventeenth problem is one of the 23 Hilbert problems set out in a celebrated list compiled in 1900 by David Hilbert. It concerns the expression of positive definite rational functions as sums of quotients of squares. The original question may be reformulated as: Given a multivariate polynomial … See more The formulation of the question takes into account that there are non-negative polynomials, for example $${\displaystyle f(x,y,z)=z^{6}+x^{4}y^{2}+x^{2}y^{4}-3x^{2}y^{2}z^{2},}$$ See more • Polynomial SOS • Positive polynomial • Sum-of-squares optimization • SOS-convexity See more The particular case of n = 2 was already solved by Hilbert in 1893.
