FINITE TIME BLOWUP FOR THE FOURTH-ORDER NLS
2016
Bulletin of the Korean Mathematical Society
Preserved Fulltext
We consider the fourth-order Schrödinger equation with focusing inhomogeneous nonlinearity (−|x| −2 |u| 4 n u) in high space dimensions. Extending Glassey's virial argument, we show the finite time blowup of solutions when the energy is negative.
