一个模拟肿瘤生长的自由边界问题的分歧分析

Bifurcation analysis for a free boundary problem modeling tumor growth

Joachim Escher, Anca-Voichita Matioc

摘要:

本文讨论了一个模拟非坏死性肿瘤生长的自由边界问题,肿瘤被视为不可压缩流体,忽略组织弹性,且不存在化学抑制剂。我们重新表示的数学模型为一个算子方程,并通过使用分歧的论点,我们证明了存在的问题是不径向对称的稳态解。

英文摘要:

In this paper we deal with a free boundary problem modeling the growth of nonnecrotic tumors.The tumor is treated as an incompressible fluid, the tissue elasticity is neglected and no chemical inhibitor species are present. We re-express the mathematical model as an operator equation and by using a bifurcation argument we prove that there exist stationary solutions of the problem which are not radially symmetric.
