Abstract:

Let and be the modulus of convexity and the Domínguez-Benavides coefficient, respectively. According to these two geometric parameters, we obtain a sufficient condition for normal structure, that is, a Banach space has normal structure if for some which generalizes the known result by Gao and Prus.
