Thanks for the advice mathwonk! I don't think I've seen model logic, except in the proof of the nullstellensatz, but I'll look that up for sure. I'll probably read, Hrbacek and Jech's text, and then work my way up to Jech's monster text.
I'm currently an undergrad in math who's going to graduate next year. I'm interested in doing research in set theory (not now of course, perhaps in grad school). Unfortunately, I'm at a liberal arts school and there are no set theorists in the math department. All they offer is a naiive set...
That's an interesting question. I'll think more about it tomorrow, but maybe you'll find it interesting what I thought so far. I was thinking of a way to associate R3 with the sphere, but some points had to be removed. Let a plane in R3 map to the riemann sphere of radius x such that 0<x<r...
