摘要

在这项工作中，我们研究了一种应用于肿瘤生长的组织生长模型。该模型基于Perthame、Quirós和Vázquez在2014年提出的模型，但考虑了平流效应，例如营养物质、氧气的存在，或者可能是自推进的结果。这项工作的主要结果是该模型的不可压缩极限，它通过传递到压力定律中的奇异极限，在基于密度的模型和无几何边界问题之间架起了一座桥梁。然后证明限制对象是唯一的。

On the incompressible limit for a tumour growth model incorporating convective effects

In this work we study a tissue growth model with applications to tumour growth. The model is based on that of Perthame, Quirós, and Vázquez proposed in 2014 but incorporates the advective effects caused, for instance, by the presence of nutrients, oxygen, or, possibly, as a result of self-propulsion. The main result of this work is the incompressible limit of this model which builds a bridge between the density-based model and a geometry free-boundary problem by passing to a singular limit in the pressure law. The limiting objects are then proven to be unique.
