Sharpening Some Classical Numerical Radius Inequalities

H. R. Moradi, M. E. Omidvar, K. Shebrawi

New upper and lower bounds for the numerical radii of Hilbert space operators are given. Among our results, we prove that if $A \in B (H)$ is a hypo…

Complementary Inequalities to Improved AM-GM Inequality

H. R. Moradi, M. E. Omidvar

Following an idea of Lin, we prove that if $A$ and $B$ be two positive operators such that $0 < m I \leq A \leq m^{'} I \leq M^{'} I \leq B \leq M I$ , then \begin{equation*} {{Φ}^{2}}\left( \frac{A+B}{2…
