Abstract:

We prove that a $3$-dimensional selfdual Galois representation constructed by van Geemen and Top is isomorphic to a quadratic twist of the symmetric square of the Tate module of an elliptic curve. This is an application of our refinement of the Faltings-Serre method to $3$-dimensional $\ell$-adic selfdual representations with the ground field not equal to $\mathbf {Q}$. The proof makes use of the Faltings-Serre method and Burnside groups.
