| Abstract: |
|---|
| I will present an introduction to the theory of Borel equivalence
relations, explaining both the abstract theory of Borel reducibility and
applications to classification problems. I will focus primarily on
countable Borel equivalence relations, with the goal of presenting a
recent theorem of Hjorth about treeable equivalence relations, which in
particular shows that the structure of the countable Borel equivalence
relations under Borel reducibility is very complicated. |
