In this paper, we study the impulsive equation for nonlinear boundary va-lue problem by the monotone iterative method when some of the traditional boundary conditions are violated.
In this paper,we consider the system of Sturm-Liouville singular BVP and present a sufficient and necessary condition for the existence of positive solutions by means of the fixed point theorem for regular cones.
