In this article, we investigate the existence of positive solutions for second-order m-point boundary-value problems at resonance on the half-line (q(t) x'(t))' = f(t, x(t), x'(t)), a.e. in (0, infinity), x(0) = Sigma(m-2)(i-1)alpha(i)x(xi(i)), lim(t ->infinity) q(t) x'(t) = 0. Some existence results are obtained by using the Mawhin's coincidence theory.
