Hilbert 17th
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 It is an open question what is the smallest number $${\displaystyle v(n,d),}$$ such that any n-variate, non-negative polynomial of degree d can be written as sum of at most $${\displaystyle v(n,d)}$$ square rational … See more The particular case of n = 2 was already solved by Hilbert in 1893. The general problem was solved in the affirmative, in 1927, by Emil Artin, for positive semidefinite functions over the reals or more generally real-closed fields.

WebFor polynomial functions, these criteria are related to Hilbert's 17th problem, and have physical meaning of generalized squeezing conditions; alternatively, they may be interpreted as nonclassicality witnesses. We show that every generic nonclassical state can be detected by a polynomial that is a sum-of-squares of other polynomials.
