Some inequalities for the Euclidean oper
✍ Sever S. Dragomir πŸ“‚ Article πŸ“… 2006 πŸ› Elsevier Science 🌐 English βš– 133 KB

Some sharp bounds for the Euclidean operator radius of two bounded linear operators in Hilbert spaces are given. Their connection with Kittaneh's recent results which provide sharp upper and lower bounds for the numerical radius of linear operators are also established.
