Positive solutions for a nonlocal boundary-value problem with increasing response

G. L. Karakostas & P. Ch. Tsamatos

Abstract:
We study a nonlocal boundary-value problem for a second order ordinary differential equation. Under a monotonicity condition on the response function, we prove the existence of positive solutions.
