چکیده
|
We firstly define a seminorm on the space of bounded linear operators on a hilbert space, which generalizes the numerical radius norm. we investigate basic properties of this seminorm and prove inequalities involving it. further, for a positive element a in a unital c ∗ -algebra 21 we define a semi-norm on 21, which generalizes the a-operator semi-norm and the a-numerical radius.
