| Abstract: | Let X be a Banach space.We present some sufficient conditions for which a Banach space X has normal structure by using the modulus of U-convexity,modulus of W*-convexity and the coefficient of weak orthogonality. |
| |
| Keywords: | modulus of U-convexity uniform normal structure fixed point |
