Apr 10, 2021 · 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. Share. example to linear dynamicalsystems). We can nowutilize the concepts of subspace, basis, and dimension to clarify the diagonalization process, reveal some new results, and prove some theorems which could not be demonstrated in Section 3.3. Before proceeding, we introduce a notion that simplifies the discussionof diagonalization,and is usedThe multiplicities of the eigenvalues are important because they influence the dimension of the eigenspaces.
