Existence of Symmetric Positive Solutions for a Caputo Fractional Singular Boundary Value Problem

Abstract

In this article, we establish the symmetric positive existence for the following Caputo fractional boundary value problem \begin{align*} {}^{C}D_{0}^{\,μ}x(t)+f(t,x(t))&=0,\hspace{1cm}t\in(-1,\,1),\hspace{1cm}1<μ\leq2,\\ x(\pm1)=x'(0^{\pm})&=0, \end{align*} where ${}^{C}D_{0}^{\,μ}x(t)={}^{C}D_{0^{+}}^{\,μ}x(t)$ for $t\geq0$, ${}^{C}D_{0}^{\,μ}x(t)={}^{C}D_{0^{-}}^{\,μ}x(t)$ for $t\leq0$. Moreover, $f:(-1,\,1)\times(0,\infty)\rightarrow\mathbb{R}$ is continuous and singular at $t=-1$, $t=1$ and $x=0$. Here, ${}^{C}D_{0^{+}}^{\,μ}$ and ${}^{C}D_{0^{-}}^{\,μ}$, respectively, are Caputo fractional left and right derivatives of order $μ$.
