- Gergen Lectures ( 298 Views )For the third Gergen Lecture, Professor Laszlo will offer an informal conversation with interested students and faculty. This may include answering questions regarding prior lectures, such as details and proofs. He may also state open problems.

## Christopher Hacon : Birational geometry in characteristic $p>5$

- Gergen Lectures ( 285 Views )After the recent exciting progress in understanding the geometry of algebraic varieties over the complex numbers, it is natural to try to understand the geometry of varieties over an algebraically closed field of characteristic $p>0$. Many technical issues arise in this context. Nevertheless, there has been much recent progress. In particular, the MMP was established for 3-folds in characteristic $p>5$ by work of Birkar, Hacon, Xu and others. In this talk we will discuss some of the challenges and recent progress in this active area.
