Looking separately at each eigenvalue, we can say a matrix is diagonalizable if and only if for each eigenvalue the geometric multiplicity (dimension of eigenspace) matches the algebraic multiplicity (number of times it is a root of the characteristic polynomial). If it's a 7x7 matrix; the characteristic polynomial will have degree 7.Eigenvectors and Eigenspaces. Let A A be an n × n n × n matrix. The eigenspace corresponding to an eigenvalue λ λ of A A is defined to be Eλ = {x ∈ Cn ∣ Ax = λx} E λ = { x ∈ C n ∣ A x = λ x }. Let A A be an n × n n × n matrix. The eigenspace Eλ E λ consists of all eigenvectors corresponding to λ λ and the zero vector.A matrix is diagonalizable if and only if the algebraic multiplicity equals the geometric multiplicity of each eigenvalues. By your computations, the eigenspace of λ = 1 λ = 1 has dimension 1 1; that is, the geometric multiplicity of λ = 1 λ = 1 is 1 1, and so strictly smaller than its algebraic multiplicity. Therefore, A A is not ...

Apr 13, 2018 · It doesn't imply that dimension 0 is possible. You know by definition that the dimension of an eigenspace is at least 1.

Any detailed explanation would be appreciated. linear-algebra. eigenvalues-eigenvectors. Share.8. Here's an argument I like: the restriction of any compact operator to a subspace should be compact. However, the restriction of K K to the eigenspace V V associated with λ λ is given by. K|V: V → V Kx = λx K | V: V → V K x = λ x. If λ ≠ 0 λ ≠ 0, then the map x ↦ λx x ↦ λ x is only compact if V V is finite dimensional.The geometric multiplicity of is the dimension of the -eigenspace. In other words, dimKer(A Id). The algebraic multiplicity of is the number of times ( t) occurs as a factor of det(A tId). For example, take B = [3 1 0 3]. Then Ker(B 3Id) = Ker[0 1 0 0] is one dimensional, so the geometric multiplicity is 1. But det(B tId) = det 3 t 1 0 3 t

This is because each one has at least dimension one, there is n of them and sum of dimensions is n, if your matrix is of order n it means that the linear transformation it determines goes from and to vector spaces of dimension n.
