Category of topological vector spaces

From Wikipedia, the free encyclopedia

In mathematics, the category of topological vector spaces is the category whose objects are topological vector spaces and whose morphisms are continuous linear maps between them. This is a category because the composition of two continuous linear maps is again continuous. The category is often denoted TVect or TVS.

Fixing a topological field K, one can also consider the (sub-)category TVectK of topological vector spaces over K with continuous K-linear maps as the morphisms.

[edit] TVect is a concrete category

Like many categories, the category TVect is a concrete category, meaning its objects are sets with additional structure (i.e. a vector space structure and a topology) and its morphisms are functions preserving this structure. There are obvious forgetful functors into the category of topological spaces, the category of vector spaces and the category of sets.
