This is the introductory talk for a working group focusing on abelian surfaces over $\mathbb{Q}$.
The projects include:

- Finding explicit abelian surfaces $A$ with $End_C(A)=\mathbb{Z}$ that are provably modular.
- Finding infinitely many fake modular elliptic curves that are provably modular.
- Finding fake abelian $4$-folds $A$ over $\mathbb{Q}$ with $End_C(A)\otimes\mathbb{Q}=$ division algebra.
