topological ring

One can thus ask whether a given topological ring R is complete.

As may be expected, this produces a complete topological ring.

In the plane, split-complex numbers and dual numbers form alternative topological rings.

A topological ring is a topological module over each of its subrings.

The projective line over a ring for a topological ring may compactify it.

Endowed with the usual topology, the algebra of intervals forms a topological ring.

These examples of topological rings have the projective line as their one-point compactifications.

Every topological ring is a topological group (with respect to addition) and hence a uniform space in a natural manner.

This topological structure, together with the ring operations described above, form a topological ring.

This automatically gives R'X the structure of a topological ring (and even of a complete metric space).

Constructions of topological rings and modules (with V. I. Arnautov).

An approach to analysis based on topological groups, topological rings, and topological vector spaces.

When R is given the I-adic topology, R becomes a topological ring.

Every discrete valuation ring, being a local ring, carries a natural topology and is a topological ring.

The rational, real, complex and p-adic numbers are also topological rings (even topological fields, see below) with their standard topologies.

This leads to concepts such as topological groups, topological vector spaces, topological rings and local fields.

Let A be a topological ring, and let B be a topological A-algebra.

In mathematics, a topological module is a module over a topological ring such that scalar multiplication and addition are continuous.

The rings of formal power series and the p-adic integers are most naturally defined as completions of certain topological rings carrying I-adic topologies.

In abstract algebra, a completion is any of several related functors on rings and modules that result in complete topological rings and modules.

Let A be a (Noetherian) topological ring, that is, a ring A which is a topological space such that the operations of addition and multiplication are continuous.

As for any topological ring, one can ask whether (R, m) is complete (as a topological space); if it is not, one considers its completion, again a local ring.

For example, n-by-n matrices over the real numbers could be given either the Euclidean topology, or the Zariski topology, and in either case one would obtain a topological ring.

Then the collection of all intervals [x,y] can be identified with the topological ring formed by the direct sum of R with itself where addition and multiplication are defined component-wise.
