摘要 本文讨论了一类具有p-Laplacian算子型三点边值问题(Φ_p(y′))′+a(t)f(y)=0,y′(0)=0,y(1)-βy(η)=b,其中Φ_p(y)=│y│^(p-2)y,p>1,且b>0,0<β,η<1.通过使用不动点指数定理,在适当的条件下,建立了关于此类边值问题正解存在性的几个结论。 Abstract This paper studies the exitence of positive solutions for three--point boundary value problem with p--Laplacian (Фp(y′))′+a(t)f(y)=0,y′(0)=0,y(1)-βy(η)=b,where Фp(y)=|y|^p-2y,p〉1.By using the Fixed--point index theorem,the existence of positive solutions for the boundary va|ue problem above are established under suitable conditions.
