Résumé : 

We study the automorphism group of some classes of K-3 surfaces with
given Picard lattice of rank 2. More precisely we focus on two families of
K3 surfaces which are double covers of the plane ramified over a sextic
plane curve. The results are obtained using the technique of Pell's
equations. We also analyse some different examples obtained by G. Bini and
B. van Geemen. This is work in progress.
