Abstract

We study the property of asymptotic midpoint uniform convexity for infinite direct sums of Banach spaces, where the norm of the sum is defined by a Banach space E with a 1-unconditional basis. We show that a sum (Formula Presented) is asymptotically midpoint uniformly convex (AMUC) if and only if the spaces Xn are uniformly AMUC and E is uniformly monotone. We also show that Lp (X) is AMUC if and only if X is uniformly convex.
