关于Hilbert正多项式的构造

On Hilbert's construction of positive polynomials

Bruce Reznick

摘要:

在1888年,希尔伯特描述了如何找到一个以上的变量的实多项式,这些变量只取非负值,但不是多项式的平方和。他的解释是如此的严格,以至于直到20世纪60年代末才出现明确的例子。我们重新审视和推广希尔伯特的建设,并提出了许多这样的多项式。

英文摘要:

In 1888, Hilbert described how to find real polynomials in more than one variable which take only non-negative values but are not a sum of squares of polynomials. His construction was so restrictive that no explicit examples appeared until the late 1960s. We revisit and generalize Hilbert's construction and present many such polynomials.
