A. F. M. ter Elst, Martin Meyries, Joachim Rehberg

摘要:

本文考虑抛物型方程的混合边界条件和区域不均匀性支持在一个低维超曲面上,强制跳跃的余法向导数。只有最小的正则性假设的域和系数。证明了在适当的$L^p$ -设置下,相应的线性算子具有极大的抛物正则性.线性结果也足以处理相应的非退化拟线性问题。

英文摘要:

We consider parabolic equations with mixed boundary conditions and domain inhomogeneities supported on a lower dimensional hypersurface, enforcing a jump in the conormal derivative. Only minimal regularity assumptions on the domain and the coefficients are imposed. It is shown that the corresponding linear operator enjoys maximal parabolic regularity in a suitable $L^p$-setting. The linear results suffice to treat also the corresponding nondegenerate quasilinear problems.
