SOLITON BEHAVIOR IN THE COUPLED SYSTEM OF LANGMUIR WAVES AND TRANSVERSE WAVES
等离子体中Langmuir波、横波和离子声波相互作用过程的孤立子行为

The condition for the existence and the stability of solitons in the coupled system of Lang-muir waves and transverse waves are investigated. The method is completely nonlinear and makes use of Liapunov theory. The condition for the existence of the solitons and the criterion for the stability are found. The results we obtained recover the previous ones in the uncoupled case.
