- A Jordan block is a square matrix whose diagonal entries consist of a single scalar λ, whose superdiagonal entries are all 1, and all of whose other entries vanish12345. Every Jordan block is specified by its dimension n and its eigenvalue, and is denoted as Jλ,n2. Any block diagonal matrix whose blocks are Jordan blocks is called a Jordan matrix2. The lambdas are the eigenvalues of the matrix; they need not be distinct4. The eigenspace corresponding to this eigenvalue is 1-dimensional5.Learn more:✕This summary was generated using AI based on multiple online sources.

It is an matrix of zeroes everywhere except for the diagonal, which is filled with and for the superdiagonal, which is composed of ones. Any block diagonal matrix whose blocks are Jordan blocks is called a Jordan matrix.en.wikipedia.org/wiki/Jordan_matrixDefinition A matrix is said to be a Jordan block of dimension and eigenvalue if and only if its diagonal entries are all equal to, its supradiagonal entries are all equal to, and all its other entries are equal to. Thus, a Jordan block is completely specified by its dimension and its eigenvalue.statlect.com/matrix-algebra/Jordan-formThe outlined squares are known as "Jordan blocks". Each Jordan block contains one number lambda on its main diagonal, and ones above the main diagonal. The lambdas are the eigenvalues of the matrix; they need not be distinct.en.wikipedia.org/wiki/Jordan_normal_formSuch a matrix is called a Jordan block of size m with eigenvalue λ1. Its characteristic polynomial is (λ1 − λ)m, so the only eigenvalue is λ1, and the eigenspace corresponding to this eigenvalue is 1-dimensional. It is spanned by an eigenvector (1, 0,..., 0)T.www.math.purdue.edu/~eremenko/dvi/lect4.2a.pdf

Jordan normal form - Wikipedia
In linear algebra, a Jordan normal form, also known as a Jordan canonical form, is an upper triangular matrix of a particular form called a Jordan matrix representing a linear operator on a finite-dimensional vector space with respect to some basis. Such a matrix has each non-zero off-diagonal entry equal to 1, immediately above the main diagonal (on the superdiagonal), and with identical diagonal entries to the left and below them.

- These notes are meant to clarify the notion of a Jordan form which the book talks about in the last section of Chapter 8. In particular, we give the actual de nition of a Jordan form, which the book never quite gets to explicitly, although they do it in disguise!. We'll also talk about how to explicitly compute Jordan forms. Throughout we work with...
