... can give the same closed set.) We can now do the same for any commutative ring R. We define its maximal spectrum to be the set of maximal ideals, with the Zariski topology (the closed sets are the sets Z(I)). There is a problem. A continuous map of spaces from X to Y gives a homomorphism of their ri ...
