摘要：

In this paper, we introduce the weighted A-numerical radius. omega((A,V))(center dot) for semi-Hilbertian space operators. Further we obtain some basic properties and inequalities for. omega((A,V))(center dot), which will be matched with earlier results about. omega(A)(center dot). Moreover, we provide a refinement and generalization for inequalities obtained in [6, 16].
