Jr. Yan et Am. Zhao, OSCILLATION AND STABILITY OF LINEAR IMPULSIVE DELAY-DIFFERENTIAL EQUATIONS, Journal of mathematical analysis and applications (Print), 227(1), 1998, pp. 187-194
The main results of this paper are that the oscillation and the stabil
ity of a linear impulsive delay differential equation are equivalent r
espectively to the oscillation and the stability of a corresponding li
near delay differential equation without impulses. The results of this
paper can be used to improve and derive some of the known results in
the literature. (C) 1998 Academic Press.
