Abstract:

Random impulsive functional differential equation is a mathematical model with extensive applications. By means of Liapunov's direct
method coupled with Razumikhin technique and comparison principle, some sufficient conditions for uniformly (uniformly and ultimately,
uniformly and uniformly ultimately) p-moment boundedness of such systems are presented, where dV(t, x(t))/dt is imposed only on a little restriction even to obtain uniform boundedness and uniformly ultimate boundedness. Thus the obtained results are very convenient to apply.

Key words: Functional differential equation, Random impulses, Uniform boundedness, Ultimate boundedness, Liapunov function, Razumikhin condition
