摘要:

研究了二阶抛物型线性方程在移动区域中解的边界行为。本文的主要结果是在$C^1$和$C^{k,α}$域上的一个高阶边界Harnack不等式,条件是两个解在域的边界上消失的商与边界一样光滑.作为结果的一个结果,我们提供了抛物障碍问题中自由边界的高阶正则性的一个新的证明。

英文摘要:

We study the boundary behaviour of solutions to second order parabolic linear equations in moving domains. Our main result is a higher order boundary Harnack inequality in $C^1$ and $C^{k,α}$ domains, providing that the quotient of two solutions vanishing on the boundary of the domain is as smooth as the boundary. As a consequence of our result, we provide a new proof of higher order regularity of the free boundary in the parabolic obstacle problem.
