Abstract
In this paper, we show that certain types of domains in real Banach spaces E with dimension at least two are uniform domains. Our examples incude annulus domains, bounded convex domains C and their complements \(E{\setminus } \overline{C}\), and \(C{\setminus } \alpha \overline{C}\) for all \(0<\alpha <1\) when the zero vector \(o\in C\).
