SOME NOTES FOR TOPOLOGICAL CENTERS ON THE DUALS OF BANACH ALGEBRAS

We introduce the weak topological centers of left and right module actions and we study some of their properties. We investigate the relationship between these new concepts and the topological centers of of left and right module actions with some results in the group algebras.
