| Abstract: | In this paper, we establish the general comparison principles for IVP of impulsive differential equations with variable time. Our results extend and improve the previous comparison results obtained by V.Lak. et al and S.K.Kaul 3-7]. Using this comparison result, we construct two monotonic iterative sequences of solutions for (IVP) which converge to the minimal and maximal solutions of PBVP for impulsive differential equations with variable time. The results improve the corresponding results in 5]. |
