我们研究由排斥平均场耦合生成的一维自洽转移算子。该相互作用具有自然的解释,即一种在拥挤与均匀分布资源之间平衡的短视迁移动力学。利用概率测度的分位数表示,结合自洽转移算子方法,我们证明了系统物理相关不变测度的存在性与唯一性,并通过非线性不动点方程显式刻画该测度。随后,我们证明相应的有限粒子平衡在Wasserstein距离下以最优阶收敛到连续统平衡,并建立了定量的热力学极限。
英文摘要
We study a one-dimensional self-consistent transfer operator generated by a repulsive mean-field coupling. The interaction admits a natural interpretation as a myopic relocation dynamics balancing congestion and uniformly distributed resources. Using the quantile representation of probability measures, combined with self-consistent transfer operators methods, we prove the existence and uniqueness of a physically relevant invariant measure for the system and characterize it explicitly through a nonlinear fixed-point equation. We then show that the corresponding finite-particle equilibrium converges to the continuum equilibrium with optimal order in Wasserstein distance and establish a quantitative thermodynamic limit.
