We consider the following impulsive boundary value problem, x(t)=f(t,x,x), tJ\{t1,t2,,tk}, Δx(ti)=Ii(x(ti),x(ti)), Δx(ti)=Ji(x(ti),x(ti)), i=1,2,,k, x(0)=(0), x(1)=j=1m2αjx(ηj). By using the coincidence degree theory, a general theorem concerning the problem is given. Moreover, we get a concrete existence result which can be applied more conveniently than recent results. Our results extend some work concerning the usual m-point boundary value problem at resonance without impulses.
