临界Hartree方程组基态解的存在性(英文)
The Ground State Solution of Critical Hartree System
【摘要】 本文考虑临界耦合的Hartree方程组■其中Ω是RN中带有光滑边界的有界区域,N≥3,λ,v是常数,且满足λ,v>-λ1(Ω),λ1(Ω)是(-△,H01(Ω))的第一特征值,β> 0是耦合参数,临界指标2μ*=(2N-μ)/(N-2)来源于Hardy-LittlewoodSobolev不等式,利用变分的方法证明了临界Hartree方程组基态正解的存在性.
【Abstract】 In this paper,we are interested in the following critical coupled Hartree system■where Ω■ RN(N≥3) is a smooth bounded domain,λ,v> λ1(Ω) are constants,λ1(Ω) is the first eigenvalue of(-△,H01(Ω)),β> 0 is a coupling parameter,2μ*=(2 N-μ)/(N-2) due to the HardyLittle wood-Sobolev inequality.By using the variational method,the existence of positive ground state solution of this system is proved.
