Tests for the oscillation of autonomous differential equations with bounded aftereffect
V. V. Malygina Perm National Research Polytechnic University, Perm, Russia
Abstract:
Considering autonomous delay functional differential equations, we establish some oscillation criterion that reduces the oscillation problem to computing the only root of the real-valued function defined by the coefficients of the initial equation. Using the criterion, we obtain effectively verifiable oscillation tests for equations with various aftereffects.
Keywords:
delay differential equation, oscillation, concentrated and distributed delay.
