Global existence and time decay for a bipolar Euler-Poisson system with one pressureless and undamped fluid
Young-Pil Choi, Houzhi Tang, Weiyuan Zou
We study the Cauchy problem for a three-dimensional bipolar Euler--Poisson system in which one fluid is pressureless and undamped, while the other is subject to momentum relaxation…
Hyper-reduction methods for accelerating nonlinear finite element simulations: open source implementation and reproducible benchmarks
Axel Larsson, Minji Kim, Chris Vales +4
Hyper-reduction methods have gained increasing attention for their potential to accelerate reduced order models for nonlinear systems, yet their comparative accuracy and computatio…
Global dynamics of damped Euler systems with exterior potentials
Young-Pil Choi, Houzhi Tang, Weiyuan Zou
We study the three-dimensional isothermal Euler equations with linear damping and an exterior potential. For sufficiently large damping, we prove global well-posedness for arbitrar…
Alignment with nonlinear velocity couplings: collision-avoidance and micro-to-macro mean-field limits
Young-Pil Choi, Michał Fabisiak, Jan Peszek
We investigate the pressureless fractional Euler-alignment system with nonlinear velocity couplings, referred to as the -Euler-alignment system. This model features a nonlinear…
Small inertia limit for coupled kinetic swarming models
Young-Pil Choi, Simone Fagioli, Valeria Iorio
We investigate various versions of multi-dimensional systems involving many species, modeling aggregation phenomena through nonlocal interaction terms. We establish a rigorous conn…
