摘要:

本文研究了二维有界光滑区域中具有/不具有动力源的癌细胞侵袭趋化-趋触耦合模型的Neumann问题。对于一个大类的细胞动力学源,包括零源和子逻辑源,我们检测到一个明确的条件,涉及的趋化强度,渐近“阻尼”率,和细胞的初始质量,以确保统一的时间有界性相应的诺依曼问题。我们的发现显着改善现有的二维全球存在性和有界性相关的趋化性/趋触性系统。

英文摘要:

We consider the Neumann problem for a coupled chemotaxis-haptotaxis model of cancer invasion with/without kinetic source in a 2D bounded and smooth domain. For a large class of cell kinetic sources including zero source and sub-logistic sources, we detect an explicit condition involving the chemotactic strength, the asymptotic "damping" rate, and the initial mass of cells to ensure uniform-in-time boundedness for the corresponding Neumann problem. Our finding significantly improves existing 2D global existence and boundedness in related chemotaxis-/haptotaxis systems.
