Let N be a nest on a complex separable Hilbert space H and AlgN be the associated nest algebra. In this paper, we prove that every bilocal Lie derivation from AlgN into itself is of the form A[A,T]+λA+f(A), where TAlgN, λC and f:AlgNCI is a linear map vanishing on each commutator. Moreover, we show that every bilocal Lie derivation from AlgN into itself is a Lie derivation if N is a non-atomic nest or there exists an atom E of N with dimE>1.

巢代数上的双局部李推导

ñ是复可分希尔伯特空间H上的一个巢,并且一个lGñ是关联的嵌套代数。在本文中,我们证明了每个双局部 Lie 推导一个lGñ本身是形式一个[一个,]+λ一个+F(一个), 在哪里一个lGñ,λCF一个lGñC是在每个换向器上消失的线性映射。此外,我们证明了每个双局部李推导一个lGñ入自身是一个李推导,如果ñ是一个非原子巢或存在一个原子Eñ暗淡>1.
