Numerical Ranges of Companion Matrices and Normal Operators
碩士 === 國立交通大學 === 應用數學系所 === 95 === In this thesis, we study the numerical ranges of two kinds of operators. For companion matrices, we show that the numerical range of a 3-by-3 reducible companion matrix C(p) contains the numerical range of the 2-by-2 companion matrix C((1=3)p0) if and only if the...
