摘要

摘要通过引入和求解一个新的交叉约束变分问题，建立了二维广义Davey-Stewartson系统中孤子的规定质量与频率的一一对应关系。证明了小土基随频率变化的轨道稳定性。不同速度的多孤子是由稳定的小孤子构成的。

Small solitons and multisolitons in the generalized Davey-Stewartson system

Abstract By introducing and solving a new cross-constrained variational problem, a one-to-one correspondence from the prescribed mass to frequency of soliton is established for the generalized Davey-Stewartson system in two-dimensional space. Orbital stability of small soiltons depending on frequencies is proved. Multisolitons with different speeds are constructed by stable small solitons.
