On the incompressible limit of Keller-Segel system with volume-filling effects

Q He, M Zhang - arXiv preprint arXiv:2412.05884, 2024 - arxiv.org
We consider the Keller-Segel system with a volume-filling effect and study its incompressible
limit. Due to the presence of logistic-type sensitivity, $ K= 1$ is the critical threshold. When …

A Three-dimensional tumor growth model and its boundary instability
