WebPositivity and convexity. In addition to Laurent polynomials, it is also useful to consider ﬁnite power sums p(t) = P aαtα with real exponents α∈ Rb, and real coeﬃcients aα ∈ R. As for a Laurent polynomial, we say a nonzero power sum is positive if its coeﬃcients are positive. Proposition A.2 If p(t) = P aαtα is a positive power ...
