In this paper we are interested in the following critical coupled Hartree system
$ \left\{\begin{array}{l} (-\Delta)^{s} \tilde{u}+\lambda_{1}\tilde{u} = \alpha_{1}\int_{\Omega}\frac{|\tilde{u}(z)|^{2_{\mu}^{\ast}} }{|x-z|^{\mu}}dz|\tilde{u}|^{2_{\mu}^{\ast}-2}\tilde{u}\\ \quad +\beta\int_{\Omega}\frac{|\tilde{v}(z)|^{2_{\mu}^{\ast}}} {|x-z|^{\mu}}dz|\tilde{u}|^{2_{\mu}^{\ast}-2}\tilde{u}, \ \ &&\mbox{in} \ \Omega,\\ (-\Delta)^{s} \tilde{v}+\lambda_{2}\tilde{v} = \alpha_{2}\int_{\Omega}\frac{|\tilde{v}(z)|^{2_{\mu}^{\ast}} }{|x-z|^{\mu}}dz|\tilde{v}|^{2_{\mu}^{\ast}-2}\tilde{v}\\ \quad +\beta\int_{\Omega}\frac{|\tilde{u}(z)|^{2_{\mu}^{\ast}}} {|x-z|^{\mu}}dz|\tilde{v}|^{2_{\mu}^{\ast}-2}\tilde{v}, \ \ &&\mbox{in} \ \Omega,\\ \tilde{u} = \tilde{v} = 0, \ \ && \mbox{on} \ \partial \Omega, \end{array} \right. $
where
$ 0<s<1 $
,
$ \alpha_{1}, \alpha_{2}>0 $
,
$ \beta\neq0 $
,
$ 4s<\mu<N $
,
$ 2_{\mu}^{\ast} = (2N-\mu)/(N-2s) $
,
$ \Omega\subset\mathbb{R}^N(N\geq3) $
 is a smooth bounded domain,
$ -\lambda_{1}(\Omega)<\lambda_{1}, \lambda_{2}<0 $
 with
$ \lambda_{1}(\Omega) $
 the first eigenvalue of
$ (-\Delta)^{s} $
 under the Dirichlet boundary condition. Assume that the nonlinearity and the coupling terms are both of the upper critical growth due to the Hardy–Littlewood–Sobolev inequality, by applying the Dirichlet-to-Neumann map, we are able to obtain the existence of the ground state solution of the critical coupled Hartree system.
Keywords: Hartree system, Brezis-Nirenberg problem, Hardy-Littlewood-Sobolev inequality, critical exponent.
