摘要:

本文提出了集体细胞迁移宏观模型的数值研究,重点关注一个多维无压欧拉型模型,该模型包含非局部相互作用并与趋化性耦合,且严格由微观动力学推导而来。研究了不同的机械相互作用,包括吸引-排斥效应。此外,该模型被扩展到不同细胞群体相互作用的情形。最后,通过特定设置下的参数估计分析,评估了该宏观模型的有效性及其与微观动力学的一致性。

英文摘要:

In this paper we propose a numerical study of macroscopic models for collective cell migration, focusing on a multi-dimensional pressureless Euler-type model with non-local interactions coupled with chemotaxis, rigorously derived from microscopic dynamics. Different mechanical interactions are investigated, including attraction-repulsion effects. Moreover, the model is extended to the case of different populations of interacting cells. The validity of such macroscopic model and its agreement with the microscopic dynamics is finally assessed through a parameter estimation analysis in a specific setting.
