本文研究了L2−临界聚焦非齐次非线性薛定谔方程i <$tu=−Δu−| X| −B| u| 4−2bNu,(t,x)∈R×RN,其中0 < B < 1。我们研究了当初始条件<$0 ∈H1(RN)且满足<$0 <$L2 ≥ <$0 Q <$L2时爆破解的动力学行为,其中Q是我们问题的基态解.此外,我们还得到了当ε L2= ε Q ε L2时爆破解的确定。
The purpose of this work is to study the L2−critical focusing inhomogeneous nonlinear Schrödinger equation i∂tu=−Δu−|x|−b|u|4−2bNu,(t,x)∈R×RN, with 0 < b < 1. We study the dynamical behavior for blow‐up solutions when initial date ϕ∈H1(RN) and satisfies ‖ϕ‖L2≥‖Q‖L2 , where Q is the ground state solution of our problem. Furthermore, we obtain the determination of the blow‐up solutions when ‖ϕ‖L2=‖Q‖L2 .
