### The Ax Conjecture and Degenerations

Speaker: János Kollár
3:00pm | S-101
Lecture 4. The Ax conjecture and degenerations. Originating with his studies on the logic of finite fields, James Ax conjectured that every PAC field is $C_1$. The recent proof of this in characteristic 0 is connected with degenerations of rationally connected...

### Rationally Connected Varieties - Introduction

Speaker: János Kollár
2:00pm | S-101
It has been known for a long time that varieties of general type are the most complicated algebraic varieties. It is only recently, however, that the correct definition of the "simplest" algebraic varieties was established. These are the rationally connected varieties....
