动力学群集模型的弱解的存在性

Existence of weak solutions to kinetic flocking models

Trygve Karper, Antoine Mellet, Konstantina Trivisa

摘要:

建立了一类动力学群集方程弱解的整体存在性。正在考虑的模型包括动力学Cucker-Smale方程与可能的非对称植绒潜力,Cucker-Smale方程与额外的强局部对齐,和一个新提出的模型Motsch和Tadmor。在分析中采用的主要工具是速度平均引理和Schauder不动点定理以及各种积分界限。

英文摘要:

We establish the global existence of weak solutions to a class of kinetic flocking equations. The models under consideration include the kinetic Cucker-Smale equation with possibly non-symmetric flocking potential, the Cucker-Smale equation with additional strong local alignment, and a newly proposed model by Motsch and Tadmor. The main tools employed in the analysis are the velocity averaging lemma and the Schauder fixed point theorem along with various integral bounds.
