Existence of ground state solutions to Kirchhoff--Choquard system in ${\mathbb{R}}^3$ with constant potentials

Hiroshi Matsuzawa

In this paper, we consider the following linearly coupled Kirchhoff--Choquard system in ${\mathbb{R}}^3$: \begin{align*} \begin{cases} -\left(a_1 + b_1\int_{\mathbb{R}^3} |\nabla u|^…
