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

topology . PROOF . Let X be a reflexive B - space , and let z be the natural

embedding of X onto X * * . Then x and x - l are isometries , and z maps the

closed unit ...

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

**sphere**is compact in the weaktopology . PROOF . Let X be a reflexive B - space , and let z be the natural

embedding of X onto X * * . Then x and x - l are isometries , and z maps the

closed unit ...

If the closed unit

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 ( S ) be

the B ...

If the closed unit

**sphere**of an infinite dimensional B - space X contains only afinite 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 ( S ) be

the B ...

Since the closed unit

If S , S * * are the closed unit

natural embedding of X into X * * , then by Theorem V . 4 . 5 , xS is X * - dense in

Since the closed unit

**sphere**S * of Y * is Y - compact ( V . 4 . 2 ) , it follows from ...If S , S * * are the closed unit

**spheres**in X , X * * , respectively , and if ~ is thenatural embedding of X into X * * , then by Theorem V . 4 . 5 , xS is X * - dense in
