Circular Numerical Range of S_n-Matrices
碩士 === 國立中央大學 === 數學系 === 103 === For an $S_n$-matrix with a circular disc as its numerical range, we want to know whether its rank-$k$ numerical range is also a circular disc. We show that, for an $S_5$-matrix $A$ with real spectrum and circular numerical range, if its associated Blaschke product $...
