Electron beam-plasma interaction in a dusty plasma with excess
  suprathermal electrons
  The existence of large-amplitude electron-acoustic solitary structures is
investigated in an unmagnetized and collisionless two-temperature dusty plasma
penetrated by an electron beam. A nonlinear pseudopotential technique is used
to investigate the occurrence of stationary-profile solitary waves, and their
parametric dependence on the electron beam and dust perturbation is discussed.
