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!)

HogBlog Omnes nuntii apti ad trahendum ex culo meoÆquus et exæquatus. Main November 15, 2003 Fundamental Groups of Topological Groups are Abelian It's a fact: the fundamental group of any topological group is abelian. Let X be a topological group, with identity element e. Let f and g be paths at e(continuous maps from the unit interval I into X, whose value at both and 1 is e). Denote the ordinary multiplication of paths with a stop: f.g is just the path obtained by following f, and then following g, and reparametrising appropriately to obtain another path. Now, there is another natural multiplication on paths, induced by the group structure of X: denote this by *, where (f*g)(t)=f(t)g(t), where juxtaposition represents the group multiplication. Since multiplication is a continuous operation, this is indeed a path at e. Now, I put it to you that this operation is well-defined not only on paths, but on homotopy classes of paths: suppose f is homotopic to f via a path homotopy F, and g is homotopic to g via a path homotopy G. Then let H(s,t)=F(s,t)G(s,t); this is again a path homotopy, between f*g and f

Topological group From Wikipedia, the free encyclopedia. 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 . (See group object ). 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; in this sense, the theory of topological groups subsumes that of ordinary groups. edit Examples 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 topological vector spaces , such as Banach spaces or Hilbert spaces , are topological groups.

In the formalist view, it is the investigation of axiomatically defined abstract structures using logic and mathematical notation; other views are described in Philosophy of mathematics.

Topology Atlas Document # taic-35 Topology Atlas Invited Contributions vol. 5 issue 1 (2000) 5-10 The concentration phenomenon and topological groups Vladimir Pestov Invited Contribution Introduction The phenomenon of concentration of measure on high-dimensional structures [ ] (also known as the geometric law of large numbers) is an important development in modern analysis and geometry, manifesting itself across a wide range of mathematical sciences, particulaly geometric functional analysis [ ], probability theory [ ], graph theory [ ], diverse fields of computer science [ ], and statistical physics [ Some of the most interesting recent developments related to concentration of measure occured in topological groups and compact G-spaces. The present author believes that those are only the tip of an iceberg and the potential for interaction of the phenomenon with topology is far greater than that, so that concentration deserves to be better known among topologists. Overview n S n . However, his results lay dormant until about 1970, when Vitali Milman [ ] realized that the famous Dvoretzky's Theorem on almost spherical sections of convex bodies is a manifestation of the concentration phenomenon on spheres.
