Size of the zero set of solutions of elliptic PDEs near the boundary of Lipschitz domains with small Lipschitz constant

Josep M. Gallegos

Let $\Omega \subset {\mathbb{R}}^d$ be a $C^1$ domain or, more generally, a Lipschitz domain with small Lipschitz constant and $A(x)$ be a $d\times d$ uniformly elliptic, symmetric matrix…
