Let $\lambda$ be an eigenvalue of matrix

with algebraic multiplicity

. A vector

with

$\displaystyle (A-\lambda E)^mv=0\,,\quad v\neq 0$

is called generalised eigenvector for eigenvalue $\lambda$ . All generalised eigenvectors together with the zero vector form a subspace of dimension

called generalised eigenspace $H_\lambda$ for eigenvalue $\lambda$ . This subspace is invariant under the linear mapping
