- 論文の詳細を見る
Initial-boundary valtme problems for the Davey-Stewartson type I equation are solved exactly.When the initial localized pulse can be expressed as a product of' functions of a single variable,the quantity which characterizes the pvrlse in the final stage is derived as a function of theparameters appearing in the initial and botmndary conditions. The ratio of the volume of rippleto the volume of the initial wave packet is also investigated. The amount of ripples generatedfrorn the initial condition is found to be an increasing function of the volume of the initial ptulse.
