Title: Nonlocal boundary-value problems for n-th order ordinary differential equations by matching solutions Author: Xueyan Liu (Baylor Univ., Waco, TX, USA Abstract: We are concerned with the existence and uniqueness of solutions to nonlocal boundary-value problems on an interval $[a,c]$ for the differential equation $y^{(n)}=f(x,y,y',\dots,y^{(n-1)})$, where $n\geq 3$. We use the method of matching solutions, with some monotonicity conditions on $f$. Submitted June 26, 2010. Published February 03, 2011. Math Subject Classifications: 34B15, 34B10.
