摘要
讨论了B(H)上初等算子的奇异值问题,根据其定义及奇异值的性质,推导出长度为2的初等算子的奇异值不等式及一些推论,所得结果推广了2009年Kittaneh F的结果.
The singular value problems of elementary operators on B(H) are discussed in this paper.Several singular value inequalities and corollaries are obtained by using the definition and the character of singular value of elementary operators whose length is two.In addition,the results obtained by Kittaneh F in 2009 are generalized.
