We study the logarithmic Schrödinger equation with the sign-changing potential function. It is known that the corresponding functional is not well defined in , but by imposing some condition on V(x), we can show that the functional is well defined in a subspace of . Then, the existence and multiplicity of solutions is obtained by using variational methods. We remark that the existence of solutions is deeply influenced by the sign of Q(x).

带势对数薛定谔方程解的存在性和多重性
我们研究具有符号变化势函数的对数薛定谔方程。众所周知,对应的泛函在,但是通过对V ( x )施加一些条件,我们可以证明泛函在. 然后,使用变分方法获得解的存在性和多重性。我们注意到解的存在性深受Q ( x )符号的影响。
