1. IntroductionIn the present paper we study the following Davey-Stewartson systemsupplemented with boundary conditionsand initial conditionwhere a = al la2, b = hi fo2, p = gi iap2, 7 = 71 iap and X = FI ixZ are complexconstallts, fi C RZ is a smooth bounded domain. The system was derived by Davey etalll] to model the evolution of a three-dimensional disturbance in the nonlinear regime ofplane Poiseuille flow (fully developed steady flow under a constallt pressure gradient betwe… 相似文献
