Graduate Workshop in Algebraic Geometry
for Women and Mathematicians of Minority Genders
A workshop to be held at Harvard and MIT on February 17-18 2018
Each day of the workshop will involve
- Morning session: two 90-minute mini-courses, which will be accessible to graduate students who have taken an introductory class in algebraic geometry.
- Lunch session: 5-minute math talks by participants on a topic they find interesting. We encourage all participants to give a talk, even if they haven't begun research yet.
- Afternoon session: concurrent TA-led sessions to work on concrete examples and open-ended problems contributed by the speakers.
On Saturday evening there will also be an informal professional development discussion over dinner.
Jennifer Balakrishnan: Explicit Coleman integration for curves
The Coleman integral is a p-adic line integral that allows for the computation of a number of interesting invariants in arithmetic geometry, including p-adic heights and regulators. Coleman integration also plays a key role in techniques for computing rational points on curves and torsion points on their Jacobians. I will present some of these applications and then describe how to carry out explicit Coleman integration on curves, based on recent joint work with Jan Tuitman. I will also give numerical examples using our Coleman integration algorithm to compute rational points on curves, as in the Chabauty-Coleman method.
Melody Chan: Tropical and algebraic curves and their moduli spaces
This will be a mini-course on tropical and algebraic curves and their moduli spaces, with an emphasis on the relationship between the two. Tropical geometry is a modern degeneration technique in algebraic geometry; it is a degeneration in which algebraic objects are replaced by entirely combinatorial ones. The theory of tropical curves is currently the one that has been fleshed out the most; we will use it as a window to look at applications of tropical geometry to enumerative and topological questions on algebraic curves and their moduli.
Angela Gibney: Vector bundles of conformal blocks on the moduli space of curves
The moduli space of stable n-pointed curves of genus g has played an important role in the literature: as a means of learning about smooth curves and their degenerations, as a model for moduli spaces generally, and as a test variety for developing theories in algebraic geometry. Conformal blocks are invariants of a curve attached to a Lie group. In particular, vector spaces of conformal blocks for G at any stable curve C can be identified with global sections of an ample line bundle on the moduli stack of G-bundles on C. These vector spaces fit together to form vector bundles, and we can use these bundles as a tool to study the moduli space of curves.
During my lecture I'll introduce the moduli space of curves and define these bundles. In the afternoon session, I'll illustrate our interest in these bundles on the moduli space through a set of problems about cones of positive cycles on the moduli space of curves.
Brooke Ullery: Measures of irrationality for algebraic varieties
The gonality of a smooth projective curve is the smallest degree of a map from the curve to the projective line. There are a few different definitions that attempt to generalize the notion of gonality to higher dimensional varieties. The intuition is that the higher these numbers, the further the variety is from being rational. We will discuss these measures of irrationality and various methods of calculating and bounding them. We’ll mainly focus on the examples of hypersurfaces and, more generally, complete intersections in projective space.
Funding and Registration
There will be a limited amount of funding for participants outside the greater Boston area. We expect to be able to provide partial travel support for some participants from within the United States. Accommodation for funded participants will be arranged by the organizers for the nights of Friday, February 17, and Saturday, February 18.
Funding will be allotted with preference to graduate students in the early years.
We would like to especially solicit applications for funding from mathematicians from under-represented groups and students at smaller schools.
The deadline to apply for funding has passed. The registration deadline is February 1, 2018.
