Core of a locally compact space

In topology, the core of a locally compact space is a cardinal invariant of a locally compact space X {\displaystyle X} , denoted by cor ⁡ ( X ) {\displaystyle \operatorname {cor} (X)} . Locally compact spaces with countable core generalize σ-compact locally compact spaces.
