This category contains results about Finite Complement Topology.
Definitions specific to this category can be found in Definitions/Finite Complement Topology.
Let $S$ be a set whose cardinality is usually specified as being infinite.
Let $\tau$ be the set of subsets of $S$ defined as:
- $H \in \tau \iff \relcomp S H \text { is finite, or } H = \O$
where $\relcomp S H$ denotes the complement of $H$ relative to $S$.
Then $\tau$ is the finite complement topology on $S$, and the topological space $T = \struct {S, \tau}$ is a finite complement space.
