An introduction to elliptic fibrations

Cecília Salgado
Universidade Federal do Rio de Janeiro
We will present a brief introduction to the theory of elliptic fibrations in 3 lectures. We will assume that the students are not familiar with elliptic curves, but we will take into consideration that a course treating such objects will happen in parallel.
The classes will be divided as follows1:
- Day 1: Elliptic curves, Weierstrass equations, reduction modulo a prime. Elliptic surfaces, first examples, singular fibers.
- Day 2: Mordell-Weil and Néron-Severi groups (lattices), torsion sections.
- Day 3: More geometry, some arithmetic and open problems involving elliptic fibrations.
The material is all contained in [2] and [3] and it would be good if the student has a first look at these references before the classes. They cover way more than we will be able to do in 3 hours. I also recommend the previous reading of the first chapter of [1], of [4] until III.3, and a browsing of the book [5].
