具有局部相互作用的布朗粒子的宏观极限

On the Macroscopic limit of Brownian Particles with local interaction

Franco Flandoli, Marta Leocata, Cristiano Ricci

摘要:

考虑了由具有局部相互作用的扩散过程组成的相互作用粒子系统,研究了非线性偏微分方程的宏观极限。很少有严格的结果存在于这个问题上,特别是显式形式的非线性是未知的。本文回顾了这一主题,一些主要的想法,以获得极限非线性偏微分方程,并提供了启发式和数值信息的精确形式的非线性,这是新的相对于文献和连贯的少数已知的信息。

英文摘要:

An interacting particle system made of diffusion processes with local interaction is considered and the macroscopic limit to a nonlinear PDE is investigated. Few rigorous results exists on this problem and in particular the explicit form of the nonlinearity is not known. The paper reviews this subject, some of the main ideas to get the limit nonlinear PDE and provides both heuristic and numerical informations on the precise form of the nonlinearity which are new with respect to the literature and coherent with the few known informations.
