Stable periodic orbits for delay differential equations with unimodal feedback

G Benedek, T Krisztin, R Szczelina - Journal of Dynamics and Differential …, 2024 - Springer
We consider delay differential equations of the form\(y^{\prime}(t)=-ay (t)+ bf (y (t-1))\) with
positive parameters a, b and a unimodal\(f:[0,\infty)\rightarrow [0, 1]\). It is assumed that the …

Analysis of Stability, Bifurcation, and Chaos in Generalized Mackey-Glass Equations

D Gupta, S Bhalekar - arXiv preprint arXiv:2411.02865, 2024 - arxiv.org
Mackey-Glass equation arises in the leukemia model. We generalize this equation to
include fractional-order derivatives in two directions. The first generalization contains one …

Existence of Invariant Measures for Delay Equations with Stochastic Negative Feedback

M Bosch, OW van Gaans, SMV Lunel - arXiv preprint arXiv:2501.00141, 2024 - arxiv.org
We provide sufficient conditions for the existence of invariant probability measures for
generic stochastic differential equations with finite time delay. Applications include the …

Sharkovskii theorem for infinite dimensional dynamical systems

A Gierzkiewicz, R Szczelina - arXiv preprint arXiv:2411.19190, 2024 - arxiv.org
We present adaptation of the relatively simple topological argument to show the existence of
many periodic orbits in a system of Delay Differential Equations. Namely, we prove a …
