摘要:
在本文中,我们研究了一个退化抛物型方程组,用于建模肠隐窝中多种细胞群体的动力学。该模型通过强耦合的反应-交叉扩散方程组描述细胞分裂、分化和迁移,其中扩散项退化。通过使用BV初值数据,我们首先考虑了系统的正则化形式,并建立了统一的BV估计。利用这些界限,我们然后取极限以获得弱解的存在性。
英文摘要:
In this work, we study a system of degenerate parabolic equations modeling the dynamics of multiple cell populations in intestinal crypts. The model describes cell division, differentiation, and migration through a strongly coupled system of reaction-cross-diffusion equations with degenerate diffusion. By working with initial data in BV, we first consider a regularized form of the system and establish uniform BV estimates. Using these bounds, we then pass to the limit to obtain the existence of weak solutions.
