论文摘要

我们研究了多孔培养基方程的自由边界,其中非局部漂移在维度为一。在假设初始数据在自由边界处具有超季度增长的假设,我们表明该解决方案在空间中是平滑的,$ c^{2,1} _ {\ loc} $的时间是及时的,然后自由边界为$ c^{2,1} _ {\ loc} $。此外,如果漂移是局部的,则解决方案和自由边界都是光滑的。

We study the free boundary of the porous medium equation with nonlocal drifts in dimension one. Under the assumption that the initial data has super-quadratic growth at the free boundary, we show that the solution is smooth in space and $C^{2,1}_{\loc}$ in time, and then the free boundary is $C^{2,1}_{\loc}$. Moreover if the drift is local, both the solution and the free boundary are smooth.
