碩士 === 國立交通大學 === 應用數學系所 === 100 === Abstract Given an n×n matrixM, the spread, φ(M), is essentially the diameter of its spectrum: φ(M) := max i;j |ρi − ρj |, where the maximal is taken over all pairs of eigenvalues (or nonzero eigenvalues in some cases) of M. We consider adjacent matrices, Laplacia...
