Résumé : In this talk we -shall discuss the existence and stability of periodic wave solutions for the classical φ4-model. In particular, we shall show the existence of at least four different branches of spatially-periodic wave solutions, which can all be written in terms of Jacobi elliptic functions. Then, we shall study their corresponding orbital (in)stability in the so-called energy space.
