In this paper. N always denotes continuous nest, and T(N)={TεL(H), TM с M; M ε N}. We describe the spectral picture of some strongly irreducible operators in T(N), and characterize the closure of the unitary orbit of the strongly irreducible operaiors in T(N). Continuous nest, Nest algebra, Strongly irreducible, Spectral picture

【期刊论文】THE (U+K)-ORBITS OF ESSENTIALLY NORMAL OPERATORS AND THEIR STRONG IRREDUCIBILITY**
纪友清, J YOUQING*, JIANG CHUNLAN*

The authors characterize the (U+K)-orbits of a class essentially normal operators and prove that some essentially normal operators with connected spectrum are strongly irreducible after a small compact perturbation. This partially answers a question of Domigo A. Herrero.
