We prove the existence of multiple non-negative solutions by studying the nature of the Nehari manifold with respect to the parameters λ and μ.Text15 pages1 file (.pdf)enAttribution 4.0 InternationalKirchhoff-type equationsFractional p-Laplace operatorNehari manifoldSingular elliptic systemMultiple positive solutionsArticle
