Existence of positive solutions for singular p-Laplacian Sturm-Liouville boundary value problems

D. D. Hai

Abstract:
We prove the existence of positive solutions of the Sturm-Liouville boundary value problem
$$\displaylines{
 -(r(t)\phi (u'))'=\lambda g(t)f(t,u),\quad t\in (0,1),\cr
 au(0)-b\phi ^{-1}(r(0))u'(0)=0,\quad cu(1)+d\phi ^{-1}(r(1))u'(1)=0,
 }$$
where $\phi (u')=|u'|^{p-2}u'$, $p>1$, $f:(0,1)\times(0,\infty )\to \mathbb{R}$ satisfies a p-sublinear condition and is allowed to be singular at u=0 with semipositone structure. Our results extend previously known results in the literature.
