摘要

本文研究如下一类非局部问题解的存在性 L0u=u(λΩQ(x,y)u(y)pdy), \mboxin Ω, L_0u =u \left(\lambda - \int_{\Omega}Q(x,y) |u(y)|^p dy \right) , \ \mbox{in} \ \Omega, 其中 ΩRN\Omega \subset \mathbb{R}^{N}N1N\geq 1,是有界连通开集,p>0p>0λ\lambda 为实参数,Q:Ω×ΩRQ:\Omega \times \Omega \to \mathbb{R} 是非负函数,且 L0:C(Ω)(Ω)L_0 : C(\overline{\Omega}) \to (\overline{\Omega}) 是非局部扩散算子。解的存在性通过分歧理论获得。

备注

In this version, we correct some mistakes in the old version, for example, in the old version was used that the inverse of operator L_0+MI is compact, which is not true. The reader will see that we assumed some additional conditions on function $Q$
