An extension of the Faltings-Serre method


Nuno Freitas


Faltings showed that a finite amount of computation is 
enough to decide whether two \ell-adic representations 
of the absolute Galois group of a number field K into GL_n(\Z_p) are isomorphic. 
Serre turned this into a practical algorithm and when n=p=2
and applied it to show there is only one isogeny class of elliptic curves
of conductor 11. Later Dieulefait--Guerberoff--Pacetti fully automatized
and implemented Serre's ideas and applied it to prove modularity
of many elliptic curves over imaginary quadratic fields. 
In this talk we will discuss possible extensions of the Faltings-Serre 
method like working with p > 3 or n=4, motivated by applications to
modularity of abelian surfaces. This is ongoing work with Lassina Dembele
and Luis Dieulefait.
