| Abstract: |
| We consider a system of nonlocal equations driven by a perturbed
periodic potential.
We construct multibump solutions that connect
one integer point to another one in a prescribed way.
In particular, heteroclinic, homoclinic
and chaotic trajectories are constructed.
The description of the stationary positions for the atom dislocation function in a
perturbed crystal,
as given by the Peierls-Nabarro model, is a particular case of the result presented. |
