On the Existence of Periodic Solutions of a System of Two Differential Equations with Pulse Influence
Ukr. Mat. Zh. - 2002. - 54, № 1. - pp. 133-137
We investigate the problem of the existence of periodic solutions of a system of two linear differential equations with pulse influence on a plane in the case where a stable knot or a stable focus is a singular point of this system.
