Dimension of an eigenspace.

It's easy to see that T(W) ⊂ W T ( W) ⊂ W, so we ca define S: W → W S: W → W by S = T|W S = T | W. Now an eigenvector of S S would be an eigenvector of T T, so S S has no eigenvectors. So S S has no real eigenvalues, which shows that dim(W) dim ( W) must be even, since a real polynomial of odd degree has a real root.

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.With the following method you can diagonalize a matrix of any dimension: 2×2, 3×3, 4×4, etc. The steps to diagonalize a matrix are: Find the eigenvalues of the matrix. Calculate the eigenvector associated with each eigenvalue. Form matrix P, whose columns are the eigenvectors of the matrix to be diagonalized.Sorted by: 28. Step 1: find eigenvalues. χA(λ) = det (A − λI) = − λ3 + 5λ2 − 8λ + 4 = − (λ − 1)(λ − 2)2. We are lucky, all eigenvalues are real. Step 2: for each eigenvalue λı, find rank of A − λıI (or, rather, nullity, dim(ker(A − λıI))) and kernel itself.1 is an eigenvalue of A A because A − I A − I is not invertible. By definition of an eigenvalue and eigenvector, it needs to satisfy Ax = λx A x = λ x, where x x is non-trivial, there can only be a non-trivial x x if A − λI A − λ I is not invertible. – JessicaK.

Remember that the eigenspace of an eigenvalue $\lambda$ is the vector space generated by the corresponding eigenvector. So, all you need to do is compute the eigenvectors and check how many linearly independent elements you can form from calculating the eigenvector.

Because the dimension of the eigenspace is 3, there must be three Jordan blocks, each one containing one entry corresponding to an eigenvector, because of the exponent 2 in the minimal polynomial the first block is 2*2, the remaining blocks must be 1*1. – Peter Melech.

Low rank ...You don't need to find particular eigenvectors if all you want is the dimension of the eigenspace. The eigenspace is the null space of $A-\lambda I$, so just find the rank of that matrix (say, by Gaussian elimination, but possibly only into non-reduced row echelon form) and subtract it from $3$ per the rank-nullity theorem.We see in the above pictures that (W ⊥) ⊥ = W.. Example. The orthogonal complement of R n is {0}, since the zero vector is the only vector that is orthogonal to all of the vectors in R n.. For the same reason, we have {0} ⊥ = R n..
