In this paper, we have proved the following two theorems: Theorem1. If T(4)∈SVEP, then τX is an analytic invariant subspace of T(2), where τ is the natural imbedding from X to X(2).Theorem 2. If T(1) is decomposable, then T is decomposable too.The authois take this opportunity to express their gratitude to the author of [2]. |
