研究一类带势的非线性Schrodinger方程iut=-△u-k(t,x)|u|^4/Nu,在二维空间中得到了其解在有限时间爆破的充分条件和其对称爆破解的L^2集中性质.
In this paper, a class of nonlinear Schrodinger equations with potential, iu,=-△u-k(t,x)|u|^4/Nu, is investigated in two-dimensional space. A sufficient condition for the solutions to blow-up in finite time is given, and L^2-concentration of blow-up solutions is proved.
