摘要 设N是复可分Hilbert空间H上的一个非平凡套且τ(N)是相应的套代数.研究了套代数τ(N)上的可乘导子以及近似可乘导子,利用投影以及分块理论证明了套代数τ(N)上的每一个可乘导子都是自动可加的.同时,证明了当H是无限维时,套代数τ(N)上的每一个近似可乘导子都是内导子. Let N be a non-trivial nest on a complex separable Hilbert space H and τ(N) be the associated nest algebra. The multiplieative derivation and approximately multiplieative derivation of τ(N) are considered. Using the projector and the theory of partisioning, the additivity of multiplieative derivation of τ(N) is proved. And when H is an infinite dimensional Hilbert space, every approximately multiplieative derivation of τ(N) is an inner derivation.
