Existence of positive solutions for three-point boundary value problems at resonance. (English) Zbl 1056.34019
The authors prove the existence of a positive solution for a second-order ordinary differential equation with a three-point boundary condition, whose nonlinearity is assumed to have at most linear growth. The proof uses the fixed-point index theory.
