Expository lectures
These slides from a 2010 conference in honor of my teacher Dick Gross give an overview of what I have been doing for the last few years. Several of the problems mentioned in them have been resolved.
I gave a 5-lecture course at the Park City Math Institute in summer 2009 on “Elliptic curves over function fields.” Here are the lecture notes.
In February of 2010 I gave a 12-hour course at the CRM in Barcelona on “Curves and Jacobians over function fields.” This was more advanced than Park City in that I discussed curves of higher genus and function fields over arbitrary (as opposed to finite) fields. The notes are under review and comments would be most welcome.
Research
Two recent papers:
- Explicit points on the Legendre curve gives a remarkably elementary construction of an elliptic curve over Fp(t) with explicit points generating a group of arbitrarily large rank. There appear to be many interesting related questions and generalizations.
- In Arithmetic of Jacobians in Artin-Schreier extensions, Rachel Pries and I study Artin-Schreier analogues of results proven in the Kummer tower in my article 2007b, Lisa Berger's thesis, and 2013a.
Students
I have projects for students at several levels. Here is an undergraduate research project (which is not as scary as it might seem at first ...). I'd be happy to talk with graduate students about projects in number theory and algebraic geometry ranging from a quick MS with good prospects for a paper to more substantial PhD projects.
Contact
My current office hours are Mondays 2:00 - 3:00 and Thursdays 3:00 - 4:00. Setting up an appointment by e-mail is the best way to see me. My assistant Sharon McDowell also has my schedule.
Etc.
