文摘In this paper, we study how the shape of the graph of a（z） affects on the number of positive solutions of -△v＋μb（z）v=a（z）vp-1＋λh（z）vq-1,inRN.（0.1） We prove for large enough λ,μ〉 0, there exist at least k＋ 1 positive solutions of the this semilinear elliptic equations where 1 ≤ q 〈 2 〈 p 〈 2＊ = 2N/（N-2） forN ≥ 3.
