The AMS’s Mathematics Research Communities (MRC) are a professional development program offering early-career mathematicians a rich array of opportunities to develop collaboration skills, build a network focused in an active research domain, and receive mentoring from leaders in that area. Funded through a generous three-year grant from the National Science Foundation, MRC is a year-long experience that includes:

Intensive one-week, hands-on research conferences in the summer;
Special Sessions at the AMS-MAA Joint Mathematics Meetings in the January following the summer conferences;
Guidance in career building;
Follow-up small-group collaborations;
Longer-term opportunities for collaboration and community building among the participants;

Over time, each participant is expected to provide feedback regarding career development and the impact of the MRC program.

Women, underrepresented minorities, and individuals from various types of institutions across the country are all encouraged to apply.

The focus of this MRC will be on problems in arithmetic geometry over fields of positive characteristic p that are amenable to an explicit approach, including the construction of examples, as well as computational exploration. Compared to algebraic geometry in characteristic 0, studying varieties over fields of characteristic p comes with new challenges (such as the failure of generic smoothness and classical vanishing theorems), but also with additional structure (such as the Frobenius morphism and point-counts over finite fields) that can be exploited. This often leads to interesting arithmetic considerations: possible topics for the workshop include isogeny classes of abelian varieties over finite fields, Galois covers of curves and lifting problems, and arithmetic dynamics.

To reflect the inherent interdisciplinary nature of arithmetic geometry, we invite early-career mathematicians with a wide range of backgrounds in number theory, algebraic geometry, and other subjects that intersect these fruitfully, such as dynamics and commutative algebra. During the workshop, the participants will formulate and investigate open problems around areas of current interest in small collaborative groups. They will benefit from the mentorship of a diverse group of senior arithmetic geometers, and from activities tailored to junior researchers. For instance, there will be two problem brainstorming sessions (at the beginning and the end), expository talks on key techniques (such as recent computational advances), and career-related group discussions.
