This category contains results about derivatives (in the context of topology).

Let $T = \left({S, \tau}\right)$ be a topological space.

Let $A \subseteq S$.

The **derivative** of $A$ in $T$ is the set of all accumulation points of $A$.

It is usually denoted on $\mathsf{Pr} \infty \mathsf{fWiki}$ as $A'$.
