The algebraic multiplicity of an eigenvalue is the number of times it appears as a root of the characteristic polynomial (i.e., the polynomial whose roots are the eigenvalues of a matrix). The geometric multiplicity of an eigenvalue is the dimension of the linear space of its associated eigenvectors (i.e., its eigenspace).The space of all vectors with eigenvalue λ λ is called an eigenspace eigenspace. It is, in fact, a vector space contained within the larger vector space V V: It contains 0V 0 V, since L0V = 0V = λ0V L 0 V = 0 V = λ 0 V, and is closed under addition and scalar multiplication by the above calculation. All other vector space properties are ...The eigenvalues are the roots of the characteristic polynomial det (A − λI) = 0. The set of eigenvectors associated to the eigenvalue λ forms the eigenspace Eλ = \nul(A − λI). 1 ≤ dimEλj ≤ mj.
