This category contains results about $\omega$-accumulation points in the context of Topology.


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

Let $A \subseteq S$.


An $\omega$-accumulation point of $A$ is a limit point $x$ of $A$ such that every open set containing $x$ also contains an infinite number of points of $A$.
