Let X be a Banach space which is uniformly convex and uniformly smooth. We introduce the lower and upper moduli of expansion of the dual mapping
J of the space X. Some estimation of certain well-known moduli (convexity,
smoothness and flatness) and two new moduli introduced in
[5] are described with this new moduli of expansion.
