Streszczenie
We consider the Choquard equation \begin{equation*} -\varDelta u+u=(I_\alpha*F(u))f(u)+|u|^{2^*-2}u \quad\ \text{in} \ \mathbb{R}^N, \end{equation*} where $N\geq 3$, $\alpha\in (0,N)$, $I_\alpha$ is the Riesz potential and $F(s)=\int_{0}^{s}f(t)\,dt$. If $f$ satisfies the general subcritical growth conditions, we obtain the existence of a positive ground state solution by a variational method.
