IMPULSIVE DIFFERENTIAL INEQUALITIES AND COMPARISON THEOREMS FOR POSITIVE SOLUTIONS OF NEUTRAL DELAY EQUATIONS
Isaac, I. O.; Zsolt Lipcsey


Abstract
It has become imperative in recent times to determine the properties of the solutions of certain mathematical equations or inequalities from the knowledge of associated inequalities or equations. In this paper, a number of oscillatory properties of the solutions of impulsive differential inequalities are established using the knowledge of those of their associated equations and what is more, some comparison theorems for the positive solutions of certain neutral delay impulsive differential equations are also formulated.
