Positive solutions to a class of Choquard type equations with a competing perturbation

Multibump positive solutions for Choquard equation with double potentials in ℝ3$$ {\mathrm{\mathbb{R}}}^3 $$

“…Recently, the existence of multiple solutions for Choquard equations with even or odd nonlinearities was established in Cingolani et al [7]. For more progress on the related study of Choquard equation, we may refer to earlier studies [8–20] for details.…”
