| contents | The Choquard equation is a partial differential equation that has gained significant interest and attention in recent decades. It is a nonlinear equation that combines elements of both the Laplace and Schrödinger operators, and it arises frequently in the study of numerous physical phenomena, from condensed matter physics to nonlinear optics.
In particular, the steady states of the Choquard equation were thoroughly investigated using a variational functional acting on the wave functions.
In this article, we introduce a dual formulation for the variational functional in terms of the potential indiced by the wave function, and use it to explore the existence of steady states of a multi-state version the Choquard equation in critical and sub-critical cases. |
