In mathematics, a topological space is feebly compact if every locally finite cover by nonempty open sets is finite. The concept was introduced by S. Mardeĉić and P. Papić in 1955.[1]
Some facts:
Every compact space is feebly compact.[1]
Every feebly compact paracompact space is compact.[citation needed]
Every feebly compact space is pseudocompact but the converse is not necessarily true.[1]
For a completely regular Hausdorff space the properties of being feebly compact and pseudocompact are equivalent.[citation needed]
Any maximal feebly compact space is submaximal.[2]
