This paper is concerned with nonlinear Choquard equations with doubly critical growth. We apply the Pohozăev-type identity to overcome loss of compactness caused by the doubly critical nonlinearities and obtain the existence of a ground state solution.

具有双临界指数的非线性 Choquard 方程的基态解

本文关注具有双临界增长的非线性 Choquard 方程。我们应用 Pohozăev 型恒等式来克服由双临界非线性引起的紧凑性损失，并获得基态解的存在性。
