On the images of the Galois representations attached to genus 2 Siegel modular forms, by Luis V. Dieulefait
We address the problem of the determination of
the images of the Galois representations attached to genus $2$ Siegel
cusp forms of level $1$ having multiplicity one. These representations are
symplectic. We prove that the images are as large as possible for
almost every prime, if the Siegel cusp form is not a Maass spezialform and
verifies two easy to check conditions.
