Abstract

In this paper the existence of unique positive solutions for system of (p,q,r)-Lapalacian Sturm-Liouville type two-point fractional order boundary vaue problems is established by an application of n-fixed point theorem of ternary operators on partially ordered metric spaces.

Highlights

  • Fractional calculus is deeply related to the dynamics of complicated real-world problems

  • Many mathematical models are accurately governed by fractional order dierential equations

  • There are certain papers and monographs dealing with the existence, uniqueness, multiple solutions and positive solutions of fractional order nonlinear boundary value problems, see [3, 6, 8, 7, 9, 13, 14, 15, 16, 17, 24, 25, 26] and references therein

Summary

Introduction

Fractional calculus is deeply related to the dynamics of complicated real-world problems. The study of turbulent ow through porous media is important for a wide range of scientic and engineering applications such as uidized bed combustion, compact heat exchangers, combustion in an inert porous matrix, high temperature gas-cooled reactors, chemical catalytic reactors [5] and drying of dierent products such as iron ore [12] To study such type of problems, Leibenson [11] introduced the following p-Laplacian equation, φp(u (t)) = f t, u(t), u (t) , where φp(τ) = |τ|p−2τ, p > 1, is the p-Laplacian operator its inverse function is denoted by φq(τ) with φq (τ). We provide an example to check the validity of our obtained results
