A strengthening of the latter is proposed as a conjecture [PS, p. 404]: In a central simple algebra with involution, a totally positive element is always a sum of hermitian squares. We explain in Section 5 how these results can be applied to study non-dimensionfree campus france beyrouth

"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.
