摘要：
The numerical range has many applications to different branches of applied science, systems theory, quantum physics, and so on. let A be a bounded operator on complex Hilbert Space, the numerical range of A is defined to be W(A) = {x*Ax: X is an element of C-n, vertical bar X vertical bar=1} In this paper, we present some properties of numerical ranges of 4x4 reducible companion matrices.
