The starting point of this research is a question of Curt McMullen : which
Salem numbers are realized as dynamical degrees of automorphisms of K3 surfaces ?
We show that this is the case for Salem numbers of degree 4, 6, 8, 12, 14 and 16.
The proofs use results on isometries of lattices, and these have other geometric
applications : for instance, to characterize the signatures of knots with a given
Alexander polynomial.
