关于标准单形上正多项式的最小值

On the minimum of a positive polynomial over the standard simplex

Gabriela Jeronimo, Daniel Perrucci

摘要:

本文给出了标准单形R^k上k元整系数多项式P的最小值的一个新的正下界,并假定P在单形R^k上为正.这个界限只依赖于变量的数量,程度和比特大小的系数P和改进的所有以前的界限为任意多项式是积极的单纯形。

英文摘要:

We present a new positive lower bound for the minimum value taken by a polynomial P with integer coefficients in k variables over the standard simplex of R^k, assuming that P is positive on the simplex. This bound depends only on the number of variables, the degree and the bitsize of the coefficients of P and improves all previous bounds for arbitrary polynomials which are positive over the simplex.
