On the uniform accuracy of implicit-explicit backward differentiation formulas (IMEX-BDF) for stiff hyperbolic relaxation systems and kinetic equations
Jingwei Hu, Ruiwen Shu
Many hyperbolic and kinetic equations contain a non-stiff convection/transport part and a stiff relaxation/collision part (characterized by the relaxation or mean free time $\varep…
Collective dynamics of opposing groups with stochastic communication
Shi Jin, Ruiwen Shu
We propose models describing the collective dynamics of two opposing groups of individuals with stochastic communication. Individuals from the same group are assumed to align in a…
Anticipation breeds alignment
Ruiwen Shu, Eitan Tadmor
We study the large-time behavior of systems driven by radial potentials, which react to anticipated positions, , with anticipation…
Flocking hydrodynamics with external potentials
Ruiwen Shu, Eitan Tadmor
We study the large-time behavior of hydrodynamic model which describes the collective behavior of continuum of agents, driven by pairwise alignment interactions with additional ext…
