+$X$ is homeomorphic to a [topological vector space](https://en.wikipedia.org/wiki/Topological_vector_space) (TVS) over $\mathbb R$.
 
 Equivalently, there exists a continuous commutative group operation $(x, y) \mapsto x + y$ on $X$, and a continuous scalar multiplication operation $\mathbb{R} \times X \to X$, $(\lambda, x) \mapsto \lambda x$, where $\mathbb{R}$ has the Euclidean topology, such that these operations together satisfy the axioms of a real vector space.
