CDC代数是一种自反算子代数,其格是完全分配可交换的。近二十年前,Gilfeather和Moore得到了CDC代数之间同构为准空间的一个充要条件。本文给出了CDC代数的导数δ是拟空间的一个充分必要条件。也就是说,δ是拟空间的当且仅当δ(R)映射R的核到R的范围对于每一个有限秩算子R。我们还在格上建立了一个充分条件,保证每一个导数都是准空间的。
A CDC algebra is a reflexive operator algebra whose lattice is completely distributive and commutative. Nearly twenty years ago, Gilfeather and Moore obtained a necessary and sufficient condition for an isomorphism between CDC algebras to be quasi-spatial. In this paper, we give a necessary and sufficient condition for a derivation δ of CDC algebras to be quasi-spatial. Namely, δ is quasi-spatial if and only if δ(R) maps the kernel of R into the range of R for each finite rank operator R. Some examples are presented to show the sharpness of the condition. We also establish a sufficient condition on the lattice that guarantees that every derivation is quasi-spatial.
