%0 Journal Article %T Nonexistence of solutions to some boundary-value problems for second-order ordinary differential equations %A George L. Karakostas %J Electronic Journal of Differential Equations %D 2012 %I Texas State University %X We present a method to obtain concrete sufficient conditions which guarantee non-existence of solutions lying into a prescribed domain of six two- or three-point boundary value problems for second-order ordinary differential equations. %K Boundary value problems %K non-existence of solutions %U http://ejde.math.txstate.edu/Volumes/2012/20/abstr.html
