摘要

本文研究如下分数阶Choquard型方程:(Δ)psu=λur2uxα+γ(Ωuqxyμdy)uq2u  in Ω,  u=0 in RNΩ, (- \Delta)_p^s\, u = \lambda\frac{|u|^{r-2}u}{|x|^\alpha}\,+\gamma \big(\int_\Omega \frac{|u|^q}{|x-y|^\mu}dy\big) |u|^{q-2}u \ \ \text{in } \Omega,\ \ u = 0 \ \text{in } \R^N \setminus \Omega, 其中Ω\OmegaRN\R^N中具有Lipschitz边界的有界域,p>1p>10<s<10<s<1N>spN>sp0αsp0\leq\alpha\leq sp0<μ<N0<\mu<Nλ,γ>0\lambda, \gamma>0prpαp\leq r\leq p^*_\alphap2q2pμ,sp\leq 2q\leq 2p_{\mu,s}^*pα=(Nα)pNspp_\alpha^*=\frac{(N-\alpha)p}{N-sp}pμ,s=(Nμ2)pNspp_{\mu,s}^*=\frac{(N-\frac{\mu}{2})p}{N-sp}分别为分数阶临界Hardy-Sobolev指数和Hardy-Littlewood-Sobolev不等式意义下的临界指数。在若干适当假设下,得到了正解与变号解。
