Definitions. A linear operator T on a vector space V is called nilpotent if Tp= T0 for some positive integer p. An n×n matrix A is called nilpotent if Ap= O for some positive integer . Give an example of a linear operator T on a finite-dimensional vector space such that T is not nilpotent, but zero is the only eigenvalue of T. Characterize all such operators.
