A. Cabada et al., Green's function and maximum principle for higher order ordinary differential equations with impulses, R MT J MATH, 30(2), 2000, pp. 435-446
We find Green's function representation of the solutions of a boundary valu
e problem for an impulsive linear differential equation of nth order. Then
we derive a maximum principle valid to develop monotone iterative technique
s for some nonlinear differential equations with impulses.
