Using a fixed point theorem of generalized cone expansion and compression we present in this paper criteria which guarantee the existence of at least two positive solutions for semi-positone three-point boundary value problems with parameter λ>0 belonging to a certain interval. 相似文献

This paper investigates the existence of positive solutions of singular multi-point boundary value problems of fourth order ordinary differential equation with p-Laplacian. A necessary and sufficient condition for the existence of C2[0,1] positive solution as well as pseudo-C3[0,1] positive solution is given by means of the fixed point theorems on cones. 相似文献

In this paper, we study the existence of countably many positive solutions for a singular multipoint boundary value problem. By using fixed-point index theory and the Leggett-Williams’ fixed-point theorem, sufficient conditions for the existence of countably many positive solutions are established. 相似文献

This paper is concerned with the property of the positive solutions for Sturm–Liouville singular boundary value problems with the linear conditions. We obtain a relation between the solutions and Green’s function. It implies a necessary condition for the C1[0,1] positive solutions. We apply the result to conclude that the given equation has no C1[0,1] positive solutions. 相似文献

In this paper we consider the operator equation in a real Banach space E with cone P:
where A = KF; here K is a e-positive, e-continuous and completely continuous operator, and F is a strictly increasing and continuous operator which is Fréchet differentiable at θ. Under certain conditions, we show that the operator equation has at least three solutions x1, x2, x3 such that x1 ∈ P, x2 ∈ (−P), x3 ∈ E\(P ∪ (−P)). Now since the third solution x3 ∈ E\(P ∪ (−P)), we call it a sign-changing solution. As an application of the main results, we investigate the existence of sign-changing
solutions for some three-point boundary value problem. 相似文献
