    "abstract": "The nonlinear dynamics of collisionless Alfven trains, including resonant\nparticle effects is studied using the kinetic nonlinear Schroedinger (KNLS)\nequation model. Numerical solutions of the KNLS reveal the dynamics of Alfven\nwaves to be sensitive to the sense of polarization as well as the angle of\npropagation with respect to the ambient magnetic field. The combined effects of\nboth wave nonlinearity and Landau damping result in the evolutionary formation\nof stationaryOA S- and arc-polarized directional and rotational\ndiscontinuities. These waveforms are freqently observed in the interplanetary\nplasma.",
