Key Concepts

Generalized Eigenvector

A generalized eigenvector for a matrix A is a nonzero vector w that satisfies (A - ?I)^p w = 0 for some positive integer p, where ? is an eigenvalue of A. This concept is essential because it extends the notion of an eigenvector to cases where A is not diagonalizable, capturing the structure of its Jordan blocks.

Jordan Canonical Form

The Jordan canonical form is a representation of a matrix that organizes it into Jordan blocks, each corresponding to an eigenvalue. In each block, generalized eigenvectors form a chain that illustrates the structure of repeated eigenvalues, and this form is critical for understanding how matrix functions, such as powers of a matrix, act on generalized eigenvectors.

Matrix Powers

Raising a matrix A to a natural number power j transforms the eigenvalues by mapping each eigenvalue ? to ?^j. The behavior of generalized eigenvectors under matrix powers is linked to this transformation, indicating that if w is a generalized eigenvector for A with eigenvalue ?, then it corresponds to the eigenvalue ?^j for A^j.

Eigenvalue Transformation under Powers

When computing powers of a matrix, the eigenvalue attached to a generalized eigenvector is raised to the corresponding power. This means that the condition defining a generalized eigenvector for A transfers to A^j, ensuring that the structure of generalized eigenvectors is preserved even as the eigenvalues themselves change.
