Predictability of Observables of Dynamical Systems
Xinyu Liu, Dongbin Xiu
We study the evolution of observables of dynamical systems. For linear systems, we show that observables satisfy a closed differential equation whose minimal order is determined by…

Numerical Approach for On-the-Fly Active Flow Control via Flow Map Learning Method
Xinyu Liu, Qifan Chen, Dongbin Xiu
We present a data-driven numerical approach for on-the-fly active flow control and demonstrate its effectiveness for drag reduction in two-dimensional incompressible flow past a cy…
