Numerical radius inequalities for Hilbert $C^*$-modules

Numerical radius inequalities for Hilbert $C^*$-modules

We present a new method for studying the numerical radius of bounded operators on Hilbert $C^*$-modules. Our method enables us to obtain some new results and generalize some known theorems for bounded operators on Hilbert spaces to bounded adjointable operators on Hilbert $C^*$-module spaces.
