Abstract: Sufficient conditions for the uniqueness of positive solutions of singular Sturm-Liouville boundary value problems

\begin{equation*}\begin{cases} (\mathrm E)\ (|u'|^{m-2}u')'+f(t,u,u')=0,\quad\text{in}\ (\theta _1,\theta _2),m\ge 2,\\ (\mathrm{BC})\begin{cases} \alpha _1u(\theta _1)-\beta _1u'(\theta _1)=0,\\ \alpha _2u(\theta _2)+\beta _2u'(\theta _2)=0, \end{cases} \end{cases} \tag{BVP} \end{equation*}

where $\alpha _i,\beta _i\ge 0$ and $\alpha _i^2+\beta _i^2\not=0$ $(i=1,2)$, are established.
