摘要 利用增生算子的性质及奇异值最大最小值原理研究了广义导算子的奇异值.给出一些奇异值不等式,推广了最近一些关于导算子的结果. Using the propertief of accretive operator and the max-min principle of singular value,the singular values of the generalized commutators are studied and some inequalities of singular value are given,which generalize recent results for commutators due to F.Kittaneh,R.Bhatia and O.Hirzalah.
