Analyticity of Bounded Solutions of Analytic State-Dependent Delay Differential Equations
Qingwen Hu
We study the analyticity of bounded solutions of systems of analytic state-dependent delay differential equations. We obtain the analyticity of solutions by transforming the system…
Global Hopf bifurcation for differential-algebraic equations with state dependent delay
Qingwen Hu
We develop a global Hopf bifurcation theory for differential equations with a state-dependent delay governed by an algebraic equation, using the -equivariant degree. We apply…
Dihedral Molecular Configurations Interacting by Lennard-Jones and Coulomb Forces
Irina Berezovik, Qingwen Hu, Wieslaw Krawcewicz
In this paper, we investigate periodic vibrations of a group of particles with a dihedral configuration in the plane governed by the Lennard-Jones and Coulomb forces. Using the gra…
Stabilization of turning processes using spindle feedback with state-dependent delay
Qingwen Hu, Huan Zhang
We develop a stabilization strategy of turning processes by means of delayed spindle control. We show that turning processes which contain intrinsic state-dependent delays can be s…
A model of regulatory dynamics with threshold-type state-dependent delay
Qingwen Hu
We model intracellular regulatory dynamics with threshold-type state-dependent delay and investigate the effect of the state-dependent diffusion time. A general model which is an e…
