Abstract: In this paper, we introduce the definition of the weighted numerical radius ??(x) for x ? E by using the linking algebra of a Hilbert C*-modules E, which extends the definition of numerical radius ?(x)… read more here.

Abstract: In this article, we present some new inequalities for numerical radius of Hilbert space operators via convex functions. Our results generalize and improve earlier results by El-Haddad and Kittaneh. Among several results, we show that… read more here.
