Expansion of harmonic functions near the boundary of Dini domains

Carlos Kenig, Zihui Zhao

Let $u$ be a harmonic function in a $C^{1}$ -Dini domain, such that $u$ vanishes on an open set of the boundary. We show that near every point in the open set, $u$ can be written uniq…

Boundary unique continuation on $C^{1}$ -Dini domains and the size of the singular set

Carlos Kenig, Zihui Zhao

Let $u$ be a harmonic function in a $C^{1}$ -Dini domain $D$ such that $u$ vanishes on a boundary surface ball $\partial D \cap B_{5 R} (0)$ . We consider an effective version of its sin…
