| Title: Some questions about abelian surfaces | ||
| Abstract: At the end of 19th century, Humbert characterised the locus of principally polarised abelian surfaces that contain elliptic curves. This locus has infinitely many irreducible components, called Humbert surfaces. The components can be indexed by natural numbers that are exponents of complementary elliptic curves. We would like to describe irreducible components for non-principally polarised abelian surfaces. In the talk, after a brief overview of principally polarised case, I will show some results based on a joint paper with R. Auffarth. I will restate some questions posed in the article and if time permits I will talk about a possible way to answer them. | ||
