Abstract

We are concerned with a type of fractional differential equations attached to boundary conditions. We investigate the existence of positive solutions and negative solutions via global bifurcation techniques.

Highlights

  • Boundary value problems of nonlinear fractional differential equations have been studied extensively in recent years

  • Little of the previous research is involved with both global bifurcation techniques and fractional differential equations

  • We will deal with fractional differential equations via global bifurcation techniques

Summary

Introduction

Boundary value problems of nonlinear fractional differential equations have been studied extensively in recent years (see, for instance, [ – ] and the references therein). Inspired by [ ], we will tackle the following fractional differential equation attached to boundary conditions: Dα +u(t) + rf (t, u(t)) = , t ∈ ( , ), tn–αu(n– )(t)|t= = tn–αu(n– )(t)|t= = · · · = tn–αu(t)|t= = u( ) = ,. (C+ ) There exists a nonnegative function a+∞ ∈ C[ , ] such that tn– ( – t)n– f (t, x) lim x→+∞. The Riemann-Liouville fractional derivative of order α > of a continuous function g : ( , +∞) → R is defined by.
