摘要:

本文研究了具有局部相互作用的一维一阶平均场博弈(MFG)的粒子近似。我们的问题包括一个系统的哈密尔顿-雅可比方程耦合的传输方程。当我们处理规划问题时,我们规定了输运方程的初始和终端分布。粒子近似建立在半离散变分问题上。首先,我们讨论半离散变分问题解的存在唯一性。接下来,我们证明了我们的离散化保留了一些以前确定的守恒量。最后,我们证明了粒子系统的逼近保持位移凸性。我们使用这最后一个属性来建立离散问题的统一估计。我们用数值例子说明了我们的结果。

英文摘要:

We study a particle approximation for one-dimensional first-order Mean-Field-Games (MFGs) with local interactions with planning conditions. Our problem comprises a system of a Hamilton-Jacobi equation coupled with a transport equation. As we deal with the planning problem, we prescribe initial and terminal distributions for the transport equation. The particle approximation builds on a semi-discrete variational problem. First, we address the existence and uniqueness of a solution to the semi-discrete variational problem. Next, we show that our discretization preserves some previously identified conserved quantities. Finally, we prove that the approximation by particle systems preserves displacement convexity. We use this last property to establish uniform estimates for the discrete problem. We illustrate our results for the discrete problem with numerical examples.
