Promoting Global Stability in Models of Quadratic Nonlinear Dynamic

Explore the challenges and advancements in characterizing global stability in fluid and plasma flow models through this 30-minute APS Physics journal club presentation. Delve into the modified "trapping SINDy" algorithm, based on the sparse identification of nonlinear dynamics method, which enables the identification of models producing only bounded trajectories. Examine various examples of varying model complexity and physical origin, including vortex shedding in the wake of a circular cylinder. Join Alan A. Kaptanoglu from the University of Washington as he presents his research, published in Physical Review Fluids, followed by a live Q&A session moderated by Jeff Eldredge from the University of California, Los Angeles. Cover topics such as global boundedness, sparse system identification, trapping theorem, and comparisons, gaining insights into this innovative approach to promoting global stability in quadratic nonlinear dynamic models.
