Why it matters

The work extends modularity machinery central to the proof of Fermat's Last Theorem from elliptic curves toward two-dimensional abelian varieties.

Limits

This is not a theorem that every abelian surface over the rational numbers is modular. The positive-proportion and hypothesis restrictions are essential.
