Purpose of eigenvalues and eigenvectors

WebGiven A∈Kn,n find a few eigenvalues and associated eigenvectors (Linear) generalized eigenvalue problem: Given A∈Cn,n, regular B∈Cn,n, seek x6=0, λ ∈C Ax= λBx ⇔ B−1Ax= λx. (4.1.3) x=ˆ generalized eigenvector, λ =ˆ generalized eigenvalue Obviously every generalized eigenvalue problem is equivalent to a standard eigenvalue problem WebTherefore, eigenvalues are the nulls of the characteristic polynomial and they are the roots of the equation χ ( λ) = 0. The characteristic polynomial is always a polynomial of degree n, where n is the dimension of the square matrix A. It can be expressed through eigenvalues: χ ( λ) = det ( λ I − A) = λ n − ( tr A) λ n − 1 + ⋯ ...
