Existence of positive solutions for singular four-point boundary value problem with a $p$ -Laplacian

Chunmei Miao, Junfang Zhao, Weigao Ge (2009)

Czechoslovak Mathematical Journal

In this paper we deal with the four-point singular boundary value problem $\{\begin{matrix} {(φ_{p} (u^{'} (t)))}^{'} + q (t) f (t, u (t), u^{'} (t)) = 0, & t \in (0, 1), \\ u^{'} (0) - α u (ξ) = 0, u^{'} (1) + β u (η) = 0, \end{matrix}$ where $φ_{p} (s) = {| s |}^{p - 2} s$ , $p > 1$ , $0 < ξ < η < 1$ , $α, β > 0$ , $q \in C [0, 1]$ , $q (t) > 0$ , $t \in (0, 1)$ , and $f \in C ([0, 1] \times (0, + \infty) \times ℝ, (0, + \infty))$ may be singular at $u = 0$ . By using the well-known theory of the Leray-Schauder degree, sufficient conditions are given for the existence of positive solutions.
