    "abstract": "An analytical model is presented for the description of nonlinear\ndust-ion-acoustic waves propagating in an unmagnetized, collisionless, three\ncomponent plasma composed of electrons, ions and inertial dust grains. The\nformulation relies on a Lagrangean approach of the plasma fluid model. The\nmodulational stability of the wave amplitude is investigated. Different types\nof localized envelope electrostatic excitations are shown to exist.",
