 Continuous linear extension - Wikipedia, the free encyclopedia
In functional analysis, it is often convenient to define something on a normed vector space by defining it on a dense set and extending it to the whole space.
The result is again linear and bounded (and thus continuous), so it is called the continuous linear extension.
Every bounded linear transformation from a normed vector space V to a complete normed vector space W can be uniquely extended to a bounded linear transformation from the completion of V to W.

 Bounded operator - Wikipedia, the free encyclopedia
In functional analysis (a branch of mathematics), a bounded linear operator is a linear transformation L between normed vector spaces X and Y for which the ratio of the norm of L(v) to that of v is bounded by the same number, over all non-zero vectors v in X.
Any linear operator between two finite-dimensional normed spaces is bounded, and such an operator may be viewed as multiplication by some fixed matrix.
First, define a linear operator on a dense subset of the domain, such that it is locally bounded.

 Extension - Wikipedia, the free encyclopedia
In general semantics, extension is a process that, as in this mathematical example, starts with unique individuals, and gives them unique names, e.g., I, II, III, etc., or 1, 2, 3, etc. The next step if needed generalizes or passes beyond extension to infinite-valued higher-order abstractions like 'numbers', and so on.
The passing from lower-order abstractions (presented extensionally) to higher orders, e.g., from '1, 2, 3, etc.,' to 'numbers,' is said to follow the 'natural order of evaluation,' so that when one talks about order, extension is implied, and when one talks about extension, order is implied.
In education, an extension course, program, or school is continuing education.

 operator norm   (Site not responding. Last check: 2007-10-19)
In functional analysis, a bounded linear operator is a linear transformation L between normed vector spaces for which the ratio of the norm of L(v) to that of v is bounded above, over all non-zero vectors v.
It is simple to prove that this is the same condition on L as continuity, for the topologies induced from the norms.
A common procedure for defining a bounded linear operator between two given complete normed spaces is as follows.

Given a field extension ''L''/''K'', ''L'' can be considered as a vector space over ''K'', with vector addition being the field addition on ''L'', and scalar multiplication being a restriction of the field multiplication on ''L''.
The extension is said to be finite or infinite according as the degree is finite or infinite.

 Apparatus for continuous casting using linear magnetic field for core agitation - Patent 4030534
As for the electromagnetic agitator for use with the continuous casting apparatus, its main body is heated to a high temperature during operation by radiant heat from the cast object and heat generated from current running in the coils.
An object of the present invention is to provide a continuous casting apparatus for producing a cast object containing a small segregation part by halting the growth of the dendrite by the agitation of the molten metal during the solidification process by means of electromagnetic induction.
Moreover, in the case of continuous casting, it is possible that in the cast object during the process of solidification, there is formed a temperature gradient because of the solidification speed being raised by forced cooling by using sprays of coolant, which gradient causes the growth of dendrite.

In topology and related areas of mathematics a continuous function is a morphism between topological spaces, that is a mapping which preserves the topological structure.
Surjective continuous functions between topological spaces are only possible if the topology of the codomain space is weaker than the topology of the domain space.
In real analysis continuity of functions is commonly defined using the ε-δ definition; which builds on the property of the real line being a metric space.

A novel method of obtaining continuous, linear phase modulation of a microwave carrier signal over the full 360 degree range is proposed.
An extension to the modulator involving phase locking or injection locking of a power oscillator is also suggested for obtaining higher power modulated output signals.
In addition to direct continuous phase modulation, the proposed method is also suitable for a wide variety of transceiver applications, including phase synchronization of antenna and oscillator arrays, phased array antenna beam steering, indirect frequency modulation, and ultra-small carrier frequency translation.

One can prove, by using the Baire category theorem, that if a linear operator L has as domain and range Banach spaces, then it will be bounded.
Thus, to give an example of a linear operator which is not bounded, we need to pick some normed spaces which are not Banach.
