摘要
研究了一类非线性GLS方程的约化涡旋动力系统,给出了2个涡旋在任意初始条件下的动力学行为的完整刻画,并利用首次积分证明出N个具有相同涡旋指标的涡旋不存在有限时间碰撞.
The GLS equation under the reduced dynamic law is studied.A complete description of the dynamic behavior of two vortices under any initial conditions is given.It is shown that N vortex centers with the same winding numbers are at least two vortices move to infinity as t→∞using first integral.
