abstract: We give examples of symplectic diffeomorphisms of R{2n}, n>2, for which the origin is a non-resonant elliptic fixed point which attracts an orbit. Based on the preprint https://hal.archives-ouvertes.fr/hal-01658860 or https://arxiv.org/abs/1712.03001v2
Joint work with Bassam Fayad and Jean-Pierre Marco
