%0 Journal Article %T Multiple positive solutions for a third-order three-point BVP with sign-changing Green's function %A Jian-Ping Sun %A Juan Zhao %J Electronic Journal of Differential Equations %D 2012 %I Texas State University %X This article concerns the third-order three-point boundary-value problem $$displaylines{ u'''(t)=f(t,u(t)),quad tin [0,1], cr u'(0)=u(1)=u''(eta)=0. }$$ Although the corresponding Green's function is sign-changing, we still obtain the existence of at least 2m-1 positive solutions for arbitrary positive integer m under suitable conditions on f. %K Third-order three-point boundary-value problem %K sign-changing Green's function %K positive solution %U http://ejde.math.txstate.edu/Volumes/2012/118/abstr.html
