Mesocompact space

In mathematics, in the field of general topology, a topological space is said to be mesocompact if every open cover has a compact-finite open refinement.¹ That is, given any open cover, we can find an open refinement with the property that every compact set meets only finitely many members of the refinement.²

The following facts are true about mesocompactness:

• Every compact space, and more generally every paracompact space is mesocompact. This follows from the fact that any locally finite cover is automatically compact-finite.
• Every mesocompact space is metacompact, and hence also orthocompact. This follows from the fact that points are compact, and hence any compact-finite cover is automatically point finite.
