Abstract
A bounded open set with boundary of class $C^1$ which is locally weakly lineally convex is weakly lineally convex, but, as shown by Yuriĭ Zelinskiĭ, this is not true for unbounded domains. The purpose here is to construct explicit examples, Hartogs domains, showing this. Their boundary can have regularity $C^{1,1}$ or $C^\infty$.
Obstructions to constructing smoothly bounded domains with certain homogeneity properties will be discussed.
