Vaught's Conjecture and Aleph_2
Abstract: Greg Hjorth proved that if there is a counterexample to Vaught's Conjecture, then there is one with no
model of size aleph_2. The proof is an interesting mix of model theory and descriptive set theory. I will
describe the proof and some of the necessary background material.
