Some inequalities for $(α, β)$ -normal operators in Hilbert spaces

Sever S. Dragomir, Mohammad Sal Moslehian

An operator $T$ acting on a Hilbert space is called $(α, β)$ -normal ( $0 \leq α \leq 1 \leq β$ ) if \begin{equation*} α^{2}T^{\ast }T\leq TT^{\ast}\leq β^{2}T^{\ast}T. \end{equation*} In…
