The space X is compact if and only if every open cover of X has a finite subcover. ... 1 Compactness is a topological property. One way to think of compact spaces is that they are somehow small—not in terms of cardinality but in terms of roominess.
Is completeness a topological property?
Completeness is not a topological property, i.e. one can't infer whether a metric space is complete just by looking at the underlying topological space.
Which is topological property?
A topological property is defined to be a property that is preserved under a homeomorphism. Examples are connectedness, compactness, and, for a plane domain, the number of components of the boundary. The most general type of objects for which homeomorphisms can be defined are topological spaces.…
