This category contains results about the union of adjacent open real intervals $\openint a b \cup \openint b c$ under the usual topology.
Let $\struct {\R, \tau_d}$ be the real number line $\R$ under the usual (Euclidean) topology $\tau_d$.
Let $a, b, c \in \R$ where $a < b < c$.
Let $A$ be the union of the two open intervals:
- $A := \openint a b \cup \openint b c$
Then $\struct {A, \tau_d}$ is the union of adjacent open intervals.
