摘要：
我们考虑一个抛物型非局部自由边界问题，该问题是作为模拟细胞极化的体-表面反应-扩散系统的极限而推导出来的。此前作者们已经证明了该问题的适定性，并进一步证明了解的唯一性以及稳态的全局稳定性。在本文中，我们研究自由边界的定性性质。我们给出了初始数据的充要条件，这些条件蕴含支集在 $t=0$ 时的连续性。如果这些假设之一不成立，则支集会发生跳跃。此外，我们还对一大类初始数据的跳跃给出了完整刻画。
英文摘要：
We consider a parabolic non-local free boundary problem that has been derived as a limit of a bulk-surface reaction-diffusion system which models cell polarization. The authors have justified the well-posedness of this problem and have further proved uniqueness of solutions and global stability of steady states. In this paper we investigate qualitative properties of the free boundary. We present necessary and sufficient conditions for the initial data that imply continuity of the support at $t = 0$. If one of these assumptions fail, then jumps of the support take place. In addition we provide a complete characterization of the jumps for a large class of initial data.
