This category contains results about Deleted Diameter Topology.

Let $\struct {\R^2, \tau_d}$ be the real number plane with the usual (Euclidean) topology induced by the Euclidean metric $d$.


Let $\BB$ be the sub-basis of $\tau_d$ defined as the set of all open balls of $\struct {\R^2, d}$ with the horizontal diameters apart from the centers excluded.

Let $\sigma$ be the topology generated from $\BB$.


$\sigma$ is referred to as the deleted diameter topology.
