On string-localized potentials and gauge fields
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
A recent idea, put forward by Mund, Rehren and Schroer, is discussed; it suggests that in gauge quantum field theory one can replace the point-localized gauge fields by string-loca…

Group bundle duality, invariants for certain C*-algebras, and twisted equivariant K-theory
Ezio Vasselli
A duality is discussed for Lie group bundles vs. certain tensor categories with non-simple identity, in the setting of Nistor-Troitsky gauge-equivariant K-theory. As an application…

Crossed products of C(X)-algebras by endomorphisms and C(X)-categories
Ezio Vasselli
We construct the crossed product of a C(X)-algebra by an endomorphism, in such a way that it becomes induced by a Hilbert C(X)-bimodule. Furthermore we introduce the notion of C(X)…
