On flat portions of some matrices
碩士 === 東吳大學 === 數學系 === 96 === Given a matrix A belong to Mn, the numerical range W(A) has a right (resp. left) vertical flat portion on its boundary if and only if 1. The hermition matrix H(A) has a multiple maximal (resp. minimal) eigenvalue λ. 2. The numbers of {x.K(A)x : x.H(A)x = λ, x . Cn, x.x...
