The Cone Generated by Positive Semidefinite Mean Polynomials

Mehdi Ghasemi, Salma Kuhlmann

We study the cone $M_{n, 2 d}$ of nonnegative mean polynomials---real $n$ -variate forms of degree $2 d$ that can be expressed as weighted power means $M_{q, p} (Y, w)$ with $q>…

Lower Bound for a Polynomial on a product of hyperellipsoids using geometric programming

Mehdi Ghasemi, Murray Marshall

Let $f$ be a polynomial in $n$ variables $x_{1}, \dots, x_{n}$ with real coefficients. In [Ghasemi-Marshal], Ghasemi and Marshall give an algorithm, based on geometric programming, which…
