趋化性动力学模型的聚集平衡态

Aggregated Steady States of a Kinetic Model for Chemotaxis

Anne Nouri, Christian Schmeiser

摘要:

考虑了一个具有准稳态化学信号吸引相互作用的动力学趋化模型。转向算子的特殊选择,与速度跳跃偏向于化学浓度梯度,允许封闭的常微分方程系统的任意阶的分布函数的时刻。系统的二阶矩表现出临界质量现象。主要结果是存在一个聚集的超临界质量的稳定状态。

英文摘要:

A kinetic chemotaxis model with attractive interaction by quasistationary chemical signalling is considered. The special choice of the turning operator, with velocity jumps biased towards the chemical concentration gradient, permits closed ODE systems for moments of the distribution function of arbitrary order. The system for second order moments exhibits a critical mass phenomeneon. The main result is existence of an aggregated steady state for supercritical mass.
