The numerical range of powers of matrices
碩士 === 東吳大學 === 數學系 === 95 === Let A be a n-by-n complex matrix; the numerical range of A is defined to be the set {x*Ax:x belongs to C^n,x*x=1}. The image of W(A^k) where k is a positive integer is studied. In particular, the geometric properties of W(A^k) related to that of W(A) are examined. Sect...
