In this paper we treat the two-variable positive extension problem for trigonometric polynomials where the extension is required to be the reciprocal of the absolute value squared of a stable ...
Let M be an archimedean quadratic module of real t×t matrix polynomials in n variables, and let S ⊆ ℝn be the set of all points where each element of M is positive semidefinite. Our key finding is a ...
