In mathematics, a topological group G is a group that is also a topological space such that the group multiplication G G → G and the inverse operation G → G are continuous maps.
http://www.wordiq.com/definition/Topological_groups

Extractions: In mathematics , a topological group G is a group that is also a topological space such that the group multiplication G G G and the inverse operation G G are continuous maps. Here, G G is viewed as a topological space by using the product topology . (In fancier language, one can say that topological groups are group objects in the category of topological spaces ). Though we do not do so here, it is common to also require that the topology on G be Hausdorff . The reasons, and some equivalent conditions, are discussed below. Almost all objects investigated in analysis are topological groups (usually with some additional structure). Every group can be trivially made into a topological group by considering it with the discrete topology ; such groups are called discrete groups . In this sense, the theory of topological groups subsumes that of ordinary groups. The real numbers R , together with addition as operation and its ordinary topology, form a topological group. More generally, Euclidean n -space R n with addition and standard topology is a topological group. More generally still, the additive groups of all

Immediate examples of topologies are and the power set of X . They are called trivial and discrete topologies, respectively. In the discrete topology, every set is open. On the other hand, and X are the only subsets that are open in the trivial topology. In application, we are usually given some set X (which often carries an intrinsic structure on its own) and then induce a topology to X by defining a according to how we want to do analysis on X . The key insight here is that saying some set is open and another closed is merely the matter of labeling. One way to induce a topology is to combine existing ones. For that, we use: 1 Lemma The intersection of topologies for the same set is again a topology for the set.

A topological group is a mathematical object with both an algebraic structure and a topological structure. Thus, one may perform algebraic operations, because of the group structure, and one may talk about continuous functions, because of the topology. Topological groups, along with continuous group actions , are used to study continuous symmetries , which have many applications, for example in physics Examples Properties ...

Extractions: POINTERS: Texts Software Web links Selected topics here Lie groups are an important special branch of group theory. They have algebraic structure, of course, and yet are also subsets of space, and so have a geometry; moreover, portions of them look just like Euclidean space, making it possible to do analysis on them (e.g. solve differential equations). Thus Lie groups and other topological groups lie at the convergence of the different areas of pure mathematics. (They are quite useful in application of mathematics to the sciences as well!)

A topological group if a topological space G together with a continuous map G x G G satisfying the usual axioms for multiplication in a group (associativity, existence of unit and existence of inverses). Topological groups form a particularly nice family of spaces, as it turns out that the group structure imposes severe restrictions on the topology. There are many natural examples of topological groups. We will mention a few here. The real and complex numbers. The real and complex numbers are examples of topological fields (and I leave it to you to figure out what that should mean). Thus each one of them has two underlying topological groups; the additive group and the multiplicative group. The additive group of the real numbers R is a connected topological group. The multiplicative group R on the other hand forms a non-connected topological group. Both the additive and the multiplicative groups of the complex numbers are connected.

Extractions: topological group (Definition) A topological group is a group \$G\$ endowed with a topology such that the multiplication and inverse operations of \$G\$ are continuous . That is, the map defined by is continuous, where the topology on is the product topology , and the map defined by is also continuous. Many authors require the topology on \$G\$ to be Hausdorff , which is equivalent to requiring that the trivial subgroup be a closed set A topology on a group \$G\$ that makes \$G\$ into a topology group is called a group topology for \$G\$ Any group becomes a topological group if it is given the discrete topology Any group becomes a topological group if it is given the indiscrete topology The real numbers with the standard topology form a topological group. More generally, an
