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.
