Abstract

This paper investigates the existence of positive solutions for m-point p-Laplacian fractional boundary value problem involving Riemann Liouville fractional integral boundary conditions on the half line via the Leray-Schauder Nonlinear Alternative theorem and the use and some properties of the Green function. As an application, an example is presented to demonstrate our main result.

Abstract

This paper is devoted to determining the eigenvalue intervals of the parameters λ1, λ2,..., λn for which there exist positive solutions of the iterative systems of second-order with m-point impulsive boundary value problem. We use the Guo-Krasnosel'skii fixed point theorem on the cones in order to achieve our results. An example is also presented to demonstrate the applicability of the main results obtained.

Abstract

In this paper, we consider a second-order m-point impulsive boundary value problem. By applying the upper and lower solutions method and the Schauder's fixed point theorem, we obtain the existence of at least one positive solution. We also give an example to illustrate our main result., Scientific and Technological Research Council of Turkey [TUBITAK-2211-A], The second author was granted a fellowship by the Scientific and Technological Research Council of Turkey (TUBITAK-2211-A).
