摘要:

该文主要研究了半无界区域上一维半线性薛定谔方程初边值问题解的破裂及其生命跨度估计.当非线性项指数p满足1 < p≤2时,证明了解在有限时间内破裂;当1 < p < 2时,进一步得到了解的生命跨度上界估计.证明的过程主要运用了试探函数方法.

关键词: 半线性薛定谔方程, 破裂, 生命跨度

Abstract:

In this paper, we consider the initial boundary value problem of semilinear Schrödinger equation on half-line. Blow up result will be established, assuming the power of the nonlinear term satisfying 1 < p≤2. Furthermore, we obtain the upper bound of the lifespan in the case 1 < p < 2. The proof is based on a contradiction argument, by constructing a special test function.

Key words: Semilinear Schrödinger equation, Blow up, Lifespan
