In this paper we are interested in the existence of ground state sign-changing solutions to the following Schrödinger–Poisson system where is a bounded smooth domain of , , and is the first eigenvalue of . Using construction technique, we show that the above system possesses one ground state sign-changing solution if and only if , which improves the recent results by Khoutir (2021).

在本文中,我们对以下薛定谔-泊松系统的基态符号变化解的存在感兴趣 在哪里 是一个有界光滑域 , , 和 是的第一个特征值 . 使用构造技术,我们证明上述系统具有一个基态符号变化解当且仅当,这改进了 Khoutir (2021) 最近的结果。
