Hilb category of Hilbert spaces
Definition 0.1.
The category Hilbf of finite-dimensional Hilbert spaces
is defined as the category whose objects are all finite-dimensional Hilbert spaces ℋf, and whose morphisms are linear maps between ℋf spaces.
The isomorphisms
in ℋilbf are all isometric isomorphisms.
Furthermore, one also has the following, general definition for any Hilbert space.
Definition 0.2.
The category Hilb of Hilbert spaces is defined as the category whose objects are all Hilbert spaces ℋ, and whose morphisms are linear maps between ℋ spaces. The isomorphisms in ℋilb are all isometric isomorphisms.
Remark 0.1.
The category of ℋilb Hilbert spaces has direct sums and is a Cartesian category.
