基于增生变换的算子不等式

Operator inequalities via accretive transforms

Mohammad Sababheh, Ibrahim Halil Gümüş, Hamid Reza Moradi

摘要:

本文利用变换$C_{M,m}(A)=(MI-A^*)(A-mI)$的某些性质,得到了复希尔伯特空间$\mathcal{H}$上有界线性算子$A$的新的不等式.特别地,我们得到了$|A|,|A^*|,|\mathfrak{R}A|$和$|\mathfrak{I}A|$之间的新关系。进一步的数值半径不等式,推广了一些已知的不等式。

英文摘要:

In this article, we employ certain properties of the transform $C_{M,m}(A)=(MI-A^*)(A-mI)$ to obtain new inequalities for the bounded linear operator $A$ on a complex Hilbert space $\mathcal{H}$. In particular, we obtain new relations among $|A|,|A^*|,|\mathfrak{R}A|$ and $|\mathfrak{I}A|$. Further numerical radius inequalities that extend some known inequalities will be presented too.
