Computing | Compact adj. Of a design, describes the valuable property that it can all be apprehended at once in one's head. This generally means the thing created from the design can be used with greater facility and fewer errors than an equivalent tool that is not compact. Compactness does not imply triviality or lack of power; for example, C is compact and FORTRAN is not, but C is more powerful than FORTRAN. Designs become non-compact through accreting features and cruft that don't merge cleanly into the overall design scheme (thus, some fans of Classic C maintain that ANSI C is no longer compact).

(From Wikipedia, the free Encyclopedia)
In mathematics, a compact space is a space that resembles a closed and bounded subset of Euclidean space Rn in that it is "small" in a certain sense and "contains all its limit points". The modern general definition calls a topological space compact if every open cover of it has a finite subcover. That is, any collection of open sets whose union is the whole space has a finite subcollection whose union is still the whole space. Some authors use the term 'quasicompact' instead and reserve the term 'compact' for compact Hausdorff spaces, but Wikipedia follows the usual current practice of allowing compact spaces to be non-Hausdorff.
Generally equivalent definitions of compact sets
An equivalent definition of compact spaces, sometimes useful, is based on the finite intersection property. This definition says that X is compact if and only if for every collection of closed sets which has the finite intersection property, the intersection over this collection is also nonempty. In other words, if all finite subsets of a collection of closed sets have nonempty intersection, so must the entire collection. For example, (0,1] is not compact, since the sequence (0,1/n] of closed sets (in (0,1]) is nested, and so clearly has the finite intersection property, but has empty intersection. This definition is used in some proofs of Tychonoff's theorem and the uncountability of the real numbers.
Equivalent definitions of a compact set in Rn
For any subset of Euclidean space Rn, the following three conditions are equivalent:
In other spaces, these conditions may or may not be equivalent, depending on the properties of the space.
- Every open cover has a finite subcover. This is the definition most commonly used, as stated above.
- Every sequence in the set has a convergent subsequence.
- Every infinite subset of the set has an accumulation point in the set.
- The set is closed and bounded. This is the condition that is easiest to verify, for example a closed interval or closed n-ball.
Examples of compact spaces
- The closed unit interval [0,1] is compact. (But not the half-open interval [0,1)).
- For every natural number n, the n-sphere is compact.
- The Cantor set is compact. (Since the p-adic integers are homeomorphic to the Cantor set, they also form a compact set.)
- Any finite topological space is compact.
- Any space carrying the cofinite topology is compact. (In the cofinite topology, a set is open iff it is empty or its complement is finite.)
- Consider the set 2N of all infinite sequences with entries in {0,1}. This is a metric space if we define d((xn),(yn)) = 1/k, where k is the smallest index such that xk ≠ yk. (If there is no such index, then the two sequences are the same, and we define their distance to be zero). Then 2N is a compact space; this is a consequence of Tychonoff's theorem mentioned below. This construction can be performed for any finite set, not just {0,1}.
- The spectrum of any continuous linear operator on a Hilbert space is a compact subset of C.
- The spectrum of any commutative ring or Boolean algebra is compact.
- The Hilbert cube is compact.
- The right order topology or left order topology on any bounded totally ordered set is compact. In particular, Sierpinski space is compact.
- The Stone-Čech compactification of any Tychonoff space is a compact Hausdorff space.
- The Alexandroff one-point compactification of any space is compact.
Theorems
Some theorems related to compactness (see the Topology Glossary for the definitions):
- A continuous image of a compact space is compact.
- A closed subset of a compact space is compact.
- A compact subset of a Hausdorff space is closed.
- A nonempty compact subset of the real numbers has a greatest element and a least element.
- A subset of Euclidean n-space is compact if and only if it is closed and bounded. (Heine-Borel theorem)
- A metric space (or uniform space) is compact if and only if it is complete and totally bounded.
- The product of any collection of compact spaces is compact. (Tychonoff's theorem -- this is equivalent to the axiom of choice)
- A compact Hausdorff space is normal.
- Every continuous bijective map from a compact space to a Hausdorff space is a homeomorphism.
- A metric space is compact if and only if every sequence in the space has a convergent subsequence.
- A topological space is compact if and only if every net on the space has a convergent subnet.
- A topological space is compact if and only if every filter on the space has a convergent refinement.
- A topological space is compact if and only if every ultrafilter on the space is convergent.
- A topological space can be embedded in a compact Hausdorff space if and only if it is a Tychonoff space.
- Every topological space X is a dense subspace of a compact space which has at most one point more than X. (Alexandroff one-point compactification)
- A metric space X is compact if and only if every metric space homeomorphic to X is complete.
- If the metric space X is compact and an open cover of X is given, then there exists a number δ > 0 such that every subset of X of diameter < δ is contained in some member of the cover. (Lebesgue's number lemma)
- If a topological space has a sub-base such that every cover of the space by members of the sub-base has a finite subcover, then the space is compact. (Alexander's Sub-base Theorem)
- Two compact Hausdorff spaces X1 and X2 are homeomorphic if and only if their rings of continuous real-valued functions C(X1) and C(X2) are isomorphic.
Other forms of compactness
There are a number of topological properties which are equivalent to compactness in metric spaces, but are inequivalent in general topological spaces. These include the following.
While all these conditions are equivalent for metric spaces, in general we have the following implications:
- Sequentially compact: Every sequence has a convergent subsequence.
- Countably compact: Every countable open cover has a finite subcover. (Or, equivalently, every infinite subset has an ω-accumulation point.)
- Pseudocompact: Every real-valued continuous function on the space is bounded.
- Weakly countably compact (or limit point compact): Every infinite subset has an accumulation point.
Compact spaces are countably compact. Sequentially compact spaces are countably compact. Countably compact spaces are pseudocompact and weakly countably compact.
Another related notion that is usually strictly weaker than compactness is local compactness.
Some history of the term compact
It has been recognized for a long time that a property like compactness was needed to prove many useful results. At one time, when primarily metric spaces were studied, compact was taken to mean the weaker sequentially compact, that every sequence has a convergent subsequence. The definition based on open coverings has surpassed it by allowing many useful results that could be proven about metric spaces using the old definition to be proven in general.
