Banach空间中的有界算子4子空间系统
BOUNDED OPERATOR FOUR SUBSPACE SYSTEMS IN BANACH SPACES
摘要
Abstract
This paper studies the bounded operator four subspaces systems ST in Banach spaces.It shows that ST and ST'are isomorphic if and only if T and T'are similar.It also shows that ST is indecomposable if and only if T is strongly irreducible.Finally,it shows that when the conjugate space X*of Banach space X is w*separable,there is an uncountable family of indecomposable bounded operator four subspace systems in X ⊕ X which are not isomorphic each other.These results are the generalizations and supplements of the corresponding results on Hilbert spaces to Banach spaces.关键词
