英文摘要:

      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].
