"A Proper Separation -- The Variety Show"

Well, it has only taken two years, but we are finally ready to give the scheme-theoretic definition of "variety".  Along the way, we discuss the notions algebraic geometers use in place of "Hausdorff" and "compact Hausdorff", namely "separated" and "proper" morphisms.  Somehow, it seems fitting to talk about "separation" as we bring this seminar to a close...

"Pseudo-finite sets and dimension, Part 2"

Having discussed the normalised counting measure on pseudo-finite sets and its application to Szemeredi Regularity, we now introduce the fine and coarse pseudo-finite dimensions for these sets, with an eye toward the Szemerdi-Trotter theorem.
