In topology, a **Hausdorff gap** (or just **gap**) is a concept relating to the structure of certain topological spaces, specifically in relation to the properties of sequences or nets in those spaces. A Hausdorff gap is often associated with the concept of a *Hausdorff space*, which is a topological space where any two distinct points can be separated by neighborhoods.
