Gichev, Todor; Angelova, Rositsa Some characteristics of a system of ordinary differential equations. (Bulgarian. English, Russian summaries) Zbl 0959.34500 God. Univ. Arkhit. Stroit. Geod. Sofiya, Svitk II, Mat. Mekh. 38(1995), 145-152 (1996). Summary: This paper is devoted to a system of linear ordinary differential equations with unbounded right-hand side. The system is related to switching in linear electrical circuits with a few switches. Formulae for initial conditions after switching and for switching loss of energy are given. An example of the switching in a circuit with two switches is also discussed. MSC: 34A37 Ordinary differential equations with impulses 94C05 Analytic circuit theory PDFBibTeX XMLCite \textit{T.
