Multiple Positive Solutions on Fourth Order Singular Boundary Value Problem
摘要
Abstract
By some abstract results of operator equation ,the fourth order singular boundary value problem was discussed. Under certain conditions on f(t,u),we find λ* ＞0 such that the problem has at least two positive solutions for λ∈ (0,λ*),atleast one positive solution for λ=λ* ,and no positive solutions for λ＞λ*.关键词
