摘要
This paper is devoted to the study of the Cauchy problem for the coupled system of the Schrodinger-KdV equations which describes the nonlinear dynamics of the one-dimensional Langmuir and ion-acoustic waves. Global well-posedness of the problem is established in the space H-k x H-k (k is an element of Z(+)), the first and second components of which correspond to the electric field of the Langmuir oscillations and the low-frequency density perturbation respectively.
