A Delay Equation Model for the Atlantic Multidecadal Oscillation
Swinda K. J. Falkena, Courtney Quinn, Jan Sieber +1
A new technique to derive delay models from systems of partial differential equations, based on the Mori-Zwanzig formalism, is used to derive a delay difference equation model for…

Calculating the Lyapunov exponents of a piecewise-smooth soft impacting system with a time-delayed feedback controller
Zhi Zhang, Yang Liu, Jan Sieber
Lyapunov exponents are a widely used tool for studying dynamical systems. When calculating Lyapunov exponents for piecewise-smooth systems with time-delayed arguments one faces a l…
