We consider the following critical nonhomogeneous Choquard equation-Δ u=\left (∫\limits _ Ω| u (y)|^ 2_ μ^*| xy|^ μ d y\right)| u|^ 2_ μ^*-2 u+ λ u+ f (x)\quad in\quad Ω,-Δ u=∫ Ω| u (y)| 2 μ∗| x-y| μ dy| u| 2 μ∗-2 u+ λ u+ f (x) in Ω, where Ω Ω is a smooth bounded domain of R^ N RN, 0 in interior of Ω Ω, λ ∈ R λ∈ R, N ≥ 7 N≥ 7, 0< μ< N 0< μ< N, 2 _ μ^*=(2N-μ)/(N-2) 2 μ∗=(2 N-μ)/(N-2) is the upper critical exponent in the sense of the Hardy–Littlewood–Sobolev inequality, and f (x) is a given function. Using variational methods, we obtain the existence of multiple solutions for the above problem when 0< λ< λ _ 1 0< λ< λ 1, where λ _ 1 λ 1 is the first eigenvalue of-Δ-Δ in H_ 0^ 1 (Ω) H 0 1 (Ω).
