We consider the nonlocal eigenvalue problem of the following form(𝒫k){𝒧Kp(x)u(x)+|u(x)|p¯(x)-2u(x)=λ|u(x)|r(x)-2u(x)inΩ,u=0in𝕉N\Ω,$$(\mathcal{P}k)\left\{ {\matrix{  {\mathcal{L}_K^{p(x)}u(x) + {{\left| {u(x)} \right|}^{\bar p(x) - 2}}u(x)} \hfill & = \hfill & {\lambda {{\left| {u(x)} \right|}^{r(x) - 2}}u(x)} \hfill & {in} \hfill & {\Omega ,} \hfill \cr  u \hfill & = \hfill & 0 \hfill & {in} \hfill & {{{\rm\mathbb{R}}^N}\backslash \Omega ,} \hfill \cr } } \right.$$where Ω is a smooth open and bounded set in 𝕉N (N ⩾ 3), λ > 0 is a real number, K is a suitable kernel and p, r are two bounded continuous functions on ̄Ω. The main result of this paper establishes that any λ > 0 sufficiently small is an eigenvalue of the above nonhomogeneous nonlocal problem. The proof relies on some variational arguments based on Ekeland's variational principle.
