Thank you, I have more questions that I'm just going to put in this thread so as not to cloud up the forum.

Is it true that contains a unique maximal ideal, but does not? I think this is the case by the correspondence theorem

Also, I can see why , but why is ? - March 18th 2009, 04:01 AMelectricjaguar
I also have a question about . Isn't one of its elements which has a root in , namely, x = 0? Doesn't this show that this element is reducible and hence the quotient is not a field?
