I have a problem that I cannot solve. I have more, but this is one of
them.
Let X be a scheme. Denote A = {global sections}. The identity on global
sections gives us a homomorphism of rings. This homomorphism gives rise
to a morphism of schemes
f: X --> Spec A
(in a standard fashion)
I wonder, is the map on the topological spaces onto?
thanks for any suggestion
