Query: Stability of Solitary Waves for Three Coupled Long Wave - Short Wave
  Interaction Equations   In this paper we consider a three-component system of one dimensional long
wave-short wave interaction equations. The system has two-parameter family of
solitary wave solutions. We prove orbital stability of the solitary wave
solutions using variational methods.
