Topic: Normed vector space



  
 Normed vector space - Wikipedia, the free encyclopedia
A semi normed vector space is a 2-tuple (V, p) where V is a vector space and p a semi norm on V.
The definition of many normed spaces (in particular, Banach spaces) involves a seminorm defined on a vector space and then the normed space is defined as the quotient space by the subspace of elements of seminorm zero.
To put it more abstractly every semi normed vector space is a topological vector space and thus carries a topological structure which is induced by the semi-norm.

 Dual space - Wikipedia, the free encyclopedia
The continuous dual V′ of a normed vector space V (e.g., a Banach space or a Hilbert space) forms a normed vector space.
This turns the continuous dual into a normed vector space, indeed into a Banach space so long as the underlying field is complete which is often included in the definition of the normed vector space.
In the language of category theory, taking the dual of vector spaces and the transpose of linear maps is therefore a contravariant functor from the category of vector spaces over F to itself.

 Seminorm - free-definition
The distinction between a seminorm and a norm (and hence between a seminormed space and a normed space) is that a seminorm may assign zero length to nonzero vectors.
The definition of many normed spaces (in particular, Banach spaces) involves a seminorm defined on a vector space and then the normed space is defined as the quotient space by the subspace of elements of seminorm zero.
In terms of the vector space, the seminorm defines a topology on the space, and this is a Hausdorff topology precisely when the seminorm can distinguish between distinct vectors, which is again equivalent to the seminorm being a norm.

 Re: Was: Convergence on a space with no topology
So if you want vector space, say you want a vector space, a normed vector space or even an inner product space.
