We study Lie ideals in unital AF Calgebras. It is shown that if a linear manifold L in an AF Calgebra A is a closed Lie ideal in A, then there exists a closed associative ideal I and a closed subalgebra EI of the canonical masa D of A such that [A,I] (?)

• 本文描述了AF C代数中闭Lie理想,证明了如果AF C代数A中的线性流形L 是A的闭Lie理想,则存在A的闭结合理想I和A的典型masa D中的闭子代数EI使得[A,I](?)
