"Webis such an example. (c) Suppose that W is a T-invariant subspace of V. Suppose that v 1+v 2∈ W, where v 1and v 2are eigenvectors of T corresponding to distinct eigenvalues. Prove that v 1and v 2both belong to W. Answer: Let w := v 1+v 2∈ W. Then T(w) = λ 1v 1+λ 2v 2∈ W, since W is T-invariant. We also have λ 1w = λ 1v 1+ λ 1v " - Findiing invariant subspace example
