本文考虑如下椭圆问题:(0.1)-Δ u+ V(x)u+ λ(κ α)|u| p)的范围内|u| p− 2 u=(κ β| u| q)的|u| q− 2 u,x∈ R 3,其中λ> 0,0< α< 3,0< β< 3,1+ α 3< p< 3+ α,q> 1且κ α(x)=| X| α− 3,κ β(x)=| X| β-3。当V= 1时,我们证明了基态解和多重解的存在性,以及(0.1)的不存在性。进一步,我们研究了(0.1)的基态解在λ→ 0+时的极限行为.当电势V不是常数时,也得到了基态解。
In this paper, we consider the following elliptic problem:(0.1)− Δ u+ V (x) u+ λ (κ α⁎| u| p)| u| p− 2 u=(κ β⁎| u| q)| u| q− 2 u, x∈ R 3, where λ> 0, 0< α< 3, 0< β< 3, 1+ α 3< p< 3+ α, q> 1 and κ α (x)=| x| α− 3, κ β (x)=| x| β− 3. If V= 1, we show the existence of a ground state solution and multiple solutions, as well as the nonexistence result for (0.1). Furthermore, we investigate the limit behavior of ground state solutions of (0.1) as λ→ 0+. Ground state solutions are also obtained if the potential V is not a constant.
