    "abstract": "Ion-acoustic modes propagating in unmagnetized dusty plasmas are studied by\napplying a generic collisionless fluid model. An Eulerian-to-Lagrangean\nvariable transformation leads to a new system of evolution equations, which may\nbe combined into a single (rather complex) equation for the mean ion density.\nThe linear and weakly nonlinear oscillations regimes are studied and their\nmodulational stability is investigated. This study extends known previous\nresults on the Lagrangian description of electron- or ion-acoustic\nelectrostatic plasma modes. The relevance with the description of dust-ion\nacoustic waves propagating in a dusty plasma is also discussed.",
