$L^p$ theory for a singular Sturm-Liouville equation

Abstract

In this paper we consider the following Sturm-Liouville equation \[ \left\{ \begin{aligned} -(x^{2α}u'(x))'+u(x)&=f(x) && \text{in } (0,1],\\ u(1)&=0 \end{aligned} \right. \] where $\alpha <1$ is a nonzero real number and $f$ belongs to $L^p(0,1)$ for $p\ge 1$. We analyze the existence and regularity of solutions under suitable weighted Dirichlet boundary condition at the origin.
