On delay differential equations with impulses. (English) Zbl 0687.34065
The authors’ summary: Sufficient conditions are obtained respectively for the asymptotic stability of the trivial solution of $$\dot x(t)+ax(t- \tau)=\sum\sp{\infty}\sb{j=1}b\sb jx(t\sb j-\tau)(t-t\sb j),\quad t\ne t\sb j,$$ and for the existence of a nonoscillatory solution; conditions are also obtained for all solutions to be oscillatory. The asymptotic behaviour of an impulsively perturbed delay-logistic equation is investigated as an extension to a nonlinear equation.
