10 Questions
| Total Attempts: 118
In mathematics, and more specifically in general topology, compactness is a property that generalizes the notion of a subset of Euclidean space being closed (that is, containing all its limit point) and bounded (that is, having all its points lie within some fixed distance of each other).
