## Infinite-dimensionality in quantum foundations: W*-algebras as presheaves over matrix algebras

14 Mar 2016 [ proceedings (QPL) ]

In this paper, W*-algebras are presented as canonical colimits of diagrams of matrix algebras and completely positive maps. In other words, matrix algebras are dense in W*-algebras.
