论文摘要
如果这是两个hurwitz稳定的$ n $ $ n $的hasamard产品(即元素乘法),则Hurwitz稳定的学位$ n \ geq1 $具有HADAMARD分解。众所周知,赫维兹稳定的稳定多项式小于四个度的多项式已分解。我们表明,对于任意$ n \ geq4 $,存在一个hurwitz稳定的$ n $多项式多项式,而不是哈达姆分解。
A Hurwitz stable polynomial of degree $n\geq1$ has a Hadamard factorization if it is a Hadamard product (i.e. element-wise multiplication) of two Hurwitz stable polynomials of degree $n$. It is known that Hurwitz stable polynomials of degrees less than four have a Hadamard factorization. We show that for arbitrary $n\geq4$ there exists a Hurwitz stable polynomial of degree $n$ which does not have a Hadamard factorization.
