肿瘤生长扩散界面模型锐界面极限的多重解

Varifold solutions of a sharp interface limit of a diffuse interface model for tumor growth

S. Melchionna, E. Rocca

摘要:

讨论了Cahn-Hilliard-Darcy耦合系统扩散界面模型的尖锐界面极限,该模型在与界面厚度相关的参数$\varepsilon>0$趋于零时模拟肿瘤生长.特别是,我们证明了当$\varepsilon$趋于零时,相关初边值问题的弱解倾向于相应尖锐界面模型的变倍解。

英文摘要:

We discuss the sharp interface limit of a diffuse interface model for a coupled Cahn-Hilliard--Darcy system that models tumor growth when a certain parameter $\varepsilon>0$, related to the interface thickness, tends to zero. In particular, we prove that weak solutions to the related initial boundary value problem tend to varifold solutions of a corresponding sharp interface model when $\varepsilon$ goes to zero.
