We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Oscillator death in coupled functional differential equations near Hopf bifurcation
Fatihcan M. Atay
Abstract
Coupled systems of functional differential equations near a supercritical Hopf bifurcation are considered, and the stability of the equilibrium solution is analyzed. Necessary and sufficient conditions are derived for the asymptotic stability of the equilibrium under general coupling conditions. The stabilizing effects of some common coupling types are investigated and the role of the frequency differences and connection delays in inducing stability is displayed. The effect of the connection topology on stability is characterized by the spectral properties of the graph Laplacian. Bounds are given for the parametric stability regions for arbitrary connection topologies.
