Cartesian decomposition and Numerical radius inequalities

Fuad Kittaneh, Mohammad Sal Moslehian, Takeaki Yamazaki

We show that if $T = H + i K$ is the Cartesian decomposition of $T \in B (H)$ , then for $α, β \in R$ , $sup_{α^{2} + β^{2} = 1} ∥ α H + β K ∥ = w (T)$ . We then apply…

Angle Preserving Mappings

Mohammad Sal Moslehian, Ali Zamani, Michael Frank

In this paper, we give some characterizations of orthogonality preserving mappings between inner product spaces. Furthermore, we study the linear mappings that preserve some angles…

Extension of Euclidean operator radius inequalities

M. S. Moslehian, M. Sattari, K. Shebrawi

To extend the Euclidean operator radius, we define $w_{p}$ for an $n$ -tuples of operators $(T_{1}, \dots, T_{n})$ in $B (H)$ by $w_p(T_1,\ldots,T_n):= \sup_{\| x \| =1}…

Squaring operator Pólya--Szegö and Diaz--Metcalf type inequalities

Mohammad Sal Moslehian, Xiaohui Fu

We square operator Pólya--Szegö and Diaz--Metcalf type inequalities as follows: If operator inequalities $0 < m_{1}^{2} \leq A \leq M_{1}^{2}$ and $0 < m_{2}^{2} \leq B \leq M_{2}^{2}$ ho…
