散度型半线性椭圆型方程解的边界Lipschitz正则性

Boundary Lipschitz regularity of solutions for semilinear elliptic equations in divergence form

Jingqi Liang, Lihe Wang, Chunqin Zhou

摘要:

本文主要在对非齐次项和边界条件较弱的假设下,研究了散度型半线性椭圆型方程解的点态边界Lipschitz正则性.若区域在边界点满足C^{1,\text{Dini} }条件,且非齐次项满足Dini连续条件和Lipschitz牛顿位势条件,则解在此点是Lipschitz连续的.进一步,我们将这个结果推广到Reifenberg C^{1,\text{Dini} }域.

英文摘要:

In this paper, we consider the pointwise boundary Lipschitz regularity of solutions for the semilinear elliptic equations in divergence form mainly under some weaker assumptions on nonhomogeneous term and the boundary. If the domain satisfies C^{1,\text{Dini}} condition at a boundary point, and the nonhomogeneous term satisfies Dini continuous condition and Lipschitz Newtonian potential condition, then the solution is Lipschitz continuous at this point. Furthermore, we generalize this result to Reifenberg C^{1,\text{Dini}} domains.
