For if I is maximal , then R / I is a commutative ring with

ideals ; by what we showed earlier R / I is a field . Conversely , if R / I is a field , it

contains no ideals and hence R has no ideals properly containing I . If R is a ring

For if I is maximal , then R / I is a commutative ring with

**unit**which has no properideals ; by what we showed earlier R / I is a field . Conversely , if R / I is a field , it

contains no ideals and hence R has no ideals properly containing I . If R is a ring

Further , from the above we see that if M is a maximal ideal in a Boolean ring R

with

**unit**, then R / M is isomorphic with the field oz . An important example of aBoolean ring with a

**unit**is the ring of subsets of a fixed set . More precisely , let Sbe ...

5 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
