Approximating characteristic equations for autonomous systems of differential equations with aftereffect
D. S. Bykov, Yu. F. Dolgii Department of Differential Equations, Institute of Mathematics and Mechanics, Ural Branch of Russian Academy of Sciences, Ekaterinburg, Russia
Abstract:
In this paper we construct approximating polynomial characteristic equations for a linear autonomous system with aftereffect. The procedures for constructing approximating characteristic equations use analytic representations of resolvents of infinitesimal operators and the theory of characteristic determinants and perturbation determinants in a separable Hilbert space.
Keywords:
differential equation with aftereffect, infinitesimal operators, resolvent, characteristic equation, approximation, characteristic determinant, perturbation determinant.
