We study the existence of positive solutions of the differential equation (-l)my(2m) (t) = f(t,y(t),y"(t), . . ,y(2(m-'))(t)) with the boundary condition Y(~~)(O) = 0 = I, 0 5 i 5 m -1, and Y(~~)(O) = 0 = y( 2i+1)(l), 0 5 i 5 m -1. We show the existence of at least one positive solution if f is eith
