Thanks!

I don't know about that specific statement (I'm not sure what you mean - the spectrum of a field is trivial...), but yeah, you can definitely narrow it down a lot. Which leads one to wonder if there is a general criterion to decide.

yes, there are many of them. these topological spaces are called

**spectral spaces**. a nice characterization is in terms of inverse limit of topological

spaces: a topological space is spectral if and only if where are finite and

i think now that you have a name, you can find other characterizations of spectral spaces.

by the way, i've assumed that by "ring" you meant "commutative ring"!
