Solvability for second-order m-point boundary value problems at resonance on the half-line

Yang Liu, Dong Li, Ming Fang

Abstract:
In this article, we investigate the existence of positive solutions for second-order m-point boundary-value problems at resonance on the half-line
$$\displaylines{ (q(t)x'(t))'=f(t,x(t),x'(t)),\quad \hbox{a.e. in }(0,\infty), \cr x(0)=\sum_{i=1}^{m-2}\alpha_ix(\xi_i),\quad \lim_{t\to \infty}q(t)x'(t)=0. }$$
Some existence results are obtained by using the Mawhin's coincidence theory.
