topological space is called locally compact if, roughly speaking, each small portion of the space looks like a small portion of a compact space. More precisely...

space is said to be σ-compact if it is the union of countably many compact subspaces. A space is said to be σ-locally compact if it is both σ-compact...

mathematics, a locally compact group is a topological group G for which the underlying topology is locally compact and Hausdorff. Locally compact groups are...

a topological space X {\displaystyle X} is called a compactly generated space or k-space if its topology is determined by compact spaces in a manner made...

Every locally normal T1 space is locally regular and locally Hausdorff. A locally compact Hausdorff space is always locally normal. A normal space is always...

while any compact Hausdorff space is locally compact, a connected space—and even a connected subset of the Euclidean plane—need not be locally connected...

of mathematics, locally convex topological vector spaces (LCTVS) or locally convex spaces are examples of topological vector spaces (TVS) that generalize...

compactness is a property that seeks to generalize the notion of a closed and bounded subset of Euclidean space. The idea is that a compact space has...

finite-dimensional vector space over the reals or a p-adic field. The Pontryagin dual of a locally compact abelian group is the locally compact abelian topological...

locally compact groups is however much weaker than the Tannaka–Krein duality theory for compact topological groups or Pontryagin duality for locally compact...

topological space is locally finite iff its a locally finite cover of the underlying locale. Every compact space is paracompact. Every regular Lindelöf space is...

representation theorem relates linear functionals on spaces of continuous functions on a locally compact space to measures in measure theory. The theorem is...

is compact. As a result, every locally compact space is core-compact. For Hausdorff spaces (or more generally, sober spaces), core-compact space is equivalent...

In algebra, a locally compact field is a topological field whose topology forms a locally compact Hausdorff space. These kinds of fields were originally...

Like all manifolds, it is locally homeomorphic to Euclidean space and thus locally metrizable (but not metrizable) and locally Hausdorff (but not Hausdorff)...

theoretical physics, a locally compact quantum group is a C*-algebraic approach toward quantum groups that generalizes the Kac algebra, compact-quantum-group and...

convergent sequence of continuous functions fn on either a metric space or a locally compact space is continuous. If, in addition, fn are holomorphic, then the...

B;E)} is an isomorphism. Let X be a locally compact topological space. (In this article, a locally compact space is understood to be Hausdorff.) For a...

space is σ-compact (i.e., a countable union of compact subsets.) If there is an exhaustion by compact sets, the space is necessarily locally compact (if...

Compactness Every product of compact spaces is compact (Tychonoff's theorem). A product of locally compact spaces need not be locally compact. However, an arbitrary...
