A B - space is reflexive if and only if its closed unit

A B - space is reflexive if and only if its closed unit

**sphere**is compact in the weak topology . PROOF . Let X be a reflexive B - space , and let z be the natural embedding of X onto X ** . Then x and 2-1 are isometries , and x maps the ...Page 458

5 If the closed unit

**sphere**of an infinite dimensional B - space X contains only a finite number of extremal points , then X is not isometrically isomorphic to the conjugate of any B - space . 6 Let S be a topological space , and let C ...Page 485

Since the closed unit

Since the closed unit

**sphere**S * of Y * is Y - compact ( V.4.2 ) , it follows from Lemma 7 and Lemma 1.5.7 that T * S ... If S , S ** are the closed unit**spheres**in X , X ** , respectively , and if x is the natural embedding of X into X ...### What people are saying - Write a review
