粗糙边界区域上抛物算子的Hölder估计

Hölder estimates for parabolic operators on domains with rough boundary

K. Disser, A. F. M. ter Elst, J. Rehberg

摘要:

研究粗糙区域上线性抛物型二阶边值问题的混合边界条件。假设只有有界性和椭圆性的系数函数和非常温和的条件上的几何域,包括一个非常弱的兼容性条件之间的Dirichlet边界部分和它的补充,我们证明了Hölder连续性的解决方案在空间和时间。

英文摘要:

We investigate linear parabolic, second-order boundary value problems with mixed boundary conditions on rough domains. Assuming only boundedness and ellipticity on the coefficient function and very mild conditions on the geometry of the domain, including a very weak compatibility condition between the Dirichlet boundary part and its complement, we prove Hölder continuity of the solution in space and time.
