Suppose A is an eigenvalue of the matrix M with associated eigenvector v. Is v an eigenvector of Mk where k is any positive integer? If so, what would the associated eigenvalue be? Now suppose that the matrix A is nilpotent, i.e. A* integer k 2. Show that 0 is the only eigenvalue of A. [Hint: what is det (A)? This should help you decide that A has an eigenvalue of 0 in particular. Then you need to demonstrate that...
