Let E be a nonempty compact set with empty interior in the complex plane, and let U ⊆ C be a bounded open set such that U ∩ E = ∅ and ∂U = E. For instance, U might be the union of all of the bounded components of C\E. We are especially interested here in the situation where E is connected and U has infinitely many connected components, and moreover where each neighborhood of each element of E c...
