Summary:
|
An $n\times n$ ray pattern $\mathcal {A}$ is called a spectrally arbitrary ray pattern if the complex matrices in $Q(\mathcal {A})$ give rise to all possible complex polynomials of degree $n$. \endgraf In a paper of Mei, Gao, Shao, and Wang (2014) was proved that the minimum number of nonzeros in an $n\times n$ irreducible spectrally arbitrary ray pattern is $3n-1$. In this paper, we introduce a new family of spectrally arbitrary ray patterns of order $n$ with exactly $3n-1$ nonzeros. (English) |
