薛定谔方程在Berestycki-Lions条件下正解的存在性
Existence of Positive Solutions of Schrödinger Equation Under the Berestycki-Lions Condition
-
摘要: 研究了一类薛定谔方程正解的存在性问题。在径向位势下, 当非线性项满足由Berestycki-Lions在1983年给出的经典条件时, 利用山路引理和对称临界原理, 得到了该问题的一个正解。Abstract: The existence of positive solutions for the Schrödinger equation with radial potential is studied. By using the mountain pass lemma and the principle of symmetric criticality, a positive solution is obtained when the nonlinear term satisfies the Berestycki-Lions condition given in 1983.
