题目：Mathematical problems in a class of tumor growth models

报告人：冯雨 (北京大学北京国际数学研究中心)

摘要：

In this talk, I will first introduce a class of tumor growth models described by porous medium equations (PME), which possesses a physical parameter m that characterizes the constitutive relation between cell density and pressure. And, one can obtain a Hele-Shaw type free boundary model by taking the incompressible limit (sending m to infinity). We then consider the forward and inverse problems in these tumor growth models. In the forward problem, we study the tumor boundary instability (the generation of finger-like structure) induced by nutrient consumption and supply based on the Hele-Shaw type model. While, in the inverse problem, we establish a Bayesian inversion framework for the PME models that perform uniformly well with respect to the constitutive relation parameter m.
