Alfvenic turbulence and small-scale structures seem to coexist at the interface between two plasmas in every boundary region of the heliosphere (shocks, magnetopauses, cusp-clefts and night side auroral regions, ionopauses…) where they have been identified by high temporal- resolution data from satellite instrumentation, e.g., Wind, Interball, Polar, Fast, Cluster and Cassini….. It is of primary importance to understand the mechanisms by which large-scale perturbations can lead to localized coherent nonlinear structures such as solitary waves, double layers, and shocks. We solicit contributions dealing with observational, numerical and theoretical studies of such filamentation processes taking place in different regions of the Heliosphere: solar corona, interplanetary space or planetary magnetospheres. This special session provides a forum to present and discuss the latest results concerning nonlinear wave-particle interaction and the development of turbulence in space plasmas.
