Abstract. In this paper we show that if T is subspace-hypercyclic or subspace-transitive with respect to a subspace M, then Tn has a dense set of irregular vectors in M for every n ∈ N. Also, we prove that if T is hyponormal or subnormal or normal or compact, for every n ∈ N, Tn can not be subspace-hypercyclic and subspace-chaotic.
