本文考虑Bose-Einstein凝聚中一类非线性Schrodinger方程.通过构造一类强制变分问题和建立两个不变发展流,解决了该方程整体解和爆破解存在所依赖的初始值的门槛条件.
We investigate a class of nonlinear Schrodinger equations in Bose-Einstein condensate. By constructing a constrained variational problem and establishing two invariant evolution flows, we obtain the threshold of global existence and blowup of the system.
