From the binomial reshuffling model to Poisson distribution of money
Fei Cao, Nicholas F. Marshall
We present a novel reshuffling exchange model and investigate its long time behavior. In this model, two individuals are picked randomly, and their wealth and are redis…
Uniform propagation of chaos for a dollar exchange econophysics model
Roberto Cortez, Fei Cao
We study the poor-biased model for money exchange introduced in [2]: agents are being randomly picked at a rate proportional to their current wealth, and then the selected agent gi…
Uncovering a two-phase dynamics from a dollar exchange model with bank and debt
Fei Cao, Sébastien Motsch
We investigate the unbiased model for money exchanges with collective debt limit: agents give at random time a dollar to one another as long as they have at least one dollar or the…
From interacting agents to Boltzmann-Gibbs distribution of money
Fei Cao, Pierre-Emmanuel Jabin
We investigate the unbiased model for money exchanges: agents give at random time a dollar to one another (if they have one). Surprisingly, this dynamics eventually leads to a geom…
Explicit decay rate for the Gini index in the repeated averaging model
Fei Cao
We investigate the repeated averaging model for money exchanges: two agents picked uniformly at random share half of their wealth to each other. It is intuitively convincing that a…
-averaging agent-based model: propagation of chaos and convergence to equilibrium
Fei Cao
The paper treats an agent-based model with averaging dynamics to which we refer as the K-averaging model. Broadly speaking, our model can be added to the growing list of dynamics e…
Derivation of wealth distributions from biased exchange of money
Fei Cao, Sebastien Motsch
In the manuscript, we are interested in using kinetic theory to better understand the time evolution of wealth distribution and their large scale behavior such as the evolution of…
Entropy dissipation and propagation of chaos for the uniform reshuffling model
Fei Cao, Pierre-Emmanuel Jabin, Sebastien Motsch
We investigate the uniform reshuffling model for money exchanges: two agents picked uniformly at random redistribute their dollars between them. This stochastic dynamics is of mean…
Optimal interpolation and Compatible Relaxation in Classical Algebraic Multigrid
James Brannick, Fei Cao, Karsten Kahl +2
In this paper, we consider a classical form of optimal algebraic multigrid (AMG) interpolation that directly minimizes the two-grid convergence rate and compare it with the so-call…
