Abstract
We discuss a non-local boundary value problem of second-order, where the involved nonlinearity depends on the derivative and may be singular. The boundary conditions are given by Riemann-Stieltjes integrals. We establish sufficient conditions for the existence of positive solutions of the considered problem. Our approach is based on the Krasnoselskii-Guo fixed point theorem on cone expansion and compression.

Summary
1 Introduction In the paper we are interested in the existence of positive solutions for the following singular non-local boundary value problem (BVP): Many interesting results on the existence of solutions for the BVPs singular in the independent and/or the dependent variables can be found in the monographs [ ] and [ ] and in the recent papers; see for example [ – ] and [ ]. Some of the techniques applied to the singular BVPs are based on the fixed point theorems in cones (see [ – ] and [ ]).
