摘要:

证明了具有Sobolev临界指数和大频率参数的组合幂型非线性标量场方程基态的唯一性。本文的研究是在文献[2]的基础上进行的,旨在消除文献[2]中对维数的限制。本文利用文献[7]中发展的不动点论证证明了这一唯一性。因此,围绕Aubin-Talenti函数的线性化起着关键作用。此外,我们需要对相关的扰动预解式进行一些估计(见命题3.1)。

英文摘要:

We prove the uniqueness of ground states for combined power-type nonlinear scalar field equations involving the Sobolev critical exponent and a large frequency parameter. This study is motivated by the paper [2] and aims to remove the restriction on dimension imposed there. In this paper, we employ the fixed-point argument developed in [7] to prove the uniquness. Hence, the linearization around the Aubin-Talenti function plays a key role. Furthermore, we need some estimates for the associated perturbed resolvents (see Proposition 3.1).
