考虑高维空间中具有非齐次非线性(−|x|−2|u|4n u)的四阶薛定谔方程。推广了Glassey的维里论点,我们证明了当能量为负时解的有限时间爆破。
We consider the fourth-order Schrodinger equation with fo- cusing inhomogeneous nonlinearity (−|x| −2 |u| 4 n u) in high space dimen- sions. Extending Glassey's virial argument, we show the finite time blow- up of solutions when the energy is negative.
