Web• if v is an eigenvector of A with eigenvalue λ, then so is αv, for any α ∈ C, α 6= 0 • even when A is real, eigenvalue λ and eigenvector v can be complex • when A and λ are real, we can always find a real eigenvector v associated with λ: if Av = λv, with A ∈ Rn×n, λ ∈ R, and v ∈ Cn, then Aℜv = λℜv, Aℑv = λℑv Weba metrized system to perturbation theory where the “smallness” of a matrix must be measured. For that reason we define metrics called matrix norms that are regular norms with one additional property pertaining to the matrix product. Definition 3.1.1.

Web1 is a complete eigenvalue if there are two linearly independent eigenvectors v 1 and v 2 corresponding to λ 1; i.e., if these two vectors are two linearly independent solutions to the system (2). In the 2 × 2 case, this only occurs when A is a scalar matrix that is, when A = λ 1 I. In this case, A − λ 1 I = 0, and every vector is an ...

Let A be an n × n matrix. An eigenvector of A is a nonzero vector v in Rn such that Av = λv, for some scalar λ. An eigenvalue of A is a scalar λ such that the equation Av = λv has a nontrivial solution.
