%0 Journal Article %T Solvability of second-order boundary-value problems at resonance involving integral conditions %A Yujun Cui %J Electronic Journal of Differential Equations %D 2012 %I Texas State University %X This article concerns the second-order differential equation with integral boundary conditions $$displaylines{ x''(t)=f(t,x(t),x'(t)),quad tin (0,1),cr x(0)=int_0^1x(s)dalpha(s),quad x(1)=int_0^1x(s)deta(s). }$$ Under the resonance conditions, we construct a projector and then applying coincidence degree theory to establish the existence of solutions. %K Coincidence degree %K integral boundary-value problem %K resonance %U http://ejde.math.txstate.edu/Volumes/2012/45/abstr.html
