The C(X)-algebra of a net and index theory
Giuseppe Ruzzi, Ezio Vasselli
Given a connected and locally compact Hausdorff space X with a good base K we assign, in a functorial way, a C(X)-algebra to any precosheaf of C*-algebras A defined over K. Afterwa…

Presheaves of superselection structures in curved spacetimes
Ezio Vasselli
We show that superselection structures on curved spacetimes, that are expected to describe quantum charges affected by the underlying geometry, are categories of sections of preshe…

Presheaves of symmetric tensor categories and nets of C*-algebras
Ezio Vasselli
Motivated by algebraic quantum field theory, we study presheaves of symmetric tensor categories defined over the base of a space, intended as a spacetime. Any section of a presheaf…
