... where Vλ is the λ-eigenspace of T on V . From the previous proposition, S stabilizes each Vλ . Let’s (re) prove that for S diagonalizable on a vector space V , that S is diagonalizable on any S-stable subspace W . Let g(x) be the minimal polynomial of S on V . Since W is S-stable, it makes sense to ...
