In this paper we study the following nonlinear Choquard equation where and is the primitive of the nonlinearity vanishing at zero. We use an asymptotic approximation approach to establish the existence of positive solutions to the above problem in the standard Sobolev space . We give a new proof and at the same time extend part of the results established in (Cassani-Tarsi, Calc.Var.PDE, 2021) [11].

具有指数非线性的平面对数 Choquard 方程的正解
在本文中,我们研究了以下非线性 Choquard 方程在哪里和是非线性的原语消失于零。我们使用渐近逼近方法来建立标准 Sobolev 空间中上述问题正解的存在性。我们给出了新的证明,同时扩展了(Cassani-Tarsi, Calc.Var.PDE, 2021) [11]中建立的部分结果。
