“…In this paper, we are focused to extend the Nehari manifold idea to discuss the multiplicity of solutions for the problem (Pλ$P_{\lambda }$) beyond the extremal value of parameter λ$\lambda ^*$ (see definition in (2.1) below), inspired by the work of Il'yasov and Silva (see [20]). It is worth mentioning the works of [10, 33, 35] in the direction of singular and Choquard problems. To study the minimizers of the energy functional scriptEλ$\mathcal {E}_\lambda$, the functional scriptEλ$\mathcal {E}_\lambda$ must be bounded from below in X 0 , which unfortunately is missing in our problem.…”

“…There are many articles pertaining to elliptic nonlocal problems driven by the Choquard term with various assumptions on the potential function V . For example, the readers may refer to Moroz-Schaftingen [8], Carvalho et al [1], Mukherjee-Sreenadh [9], and the references therein.…”
