Cheeger-Simons differential characters with compact support and Pontryagin duality
Christian Becker, Marco Benini, Alexander Schenkel +1
By adapting the Cheeger-Simons approach to differential cohomology, we establish a notion of differential cohomology with compact support. We show that it is functorial with respec…
Abelian duality on globally hyperbolic spacetimes
Christian Becker, Marco Benini, Alexander Schenkel +1
We study generalized electric/magnetic duality in Abelian gauge theory by combining techniques from locally covariant quantum field theory and Cheeger-Simons differential cohomolog…
Models of free quantum field theories on curved backgrounds
Marco Benini, Claudio Dappiaggi
Free quantum field theories on curved backgrounds are discussed via three explicit examples: the real scalar field, the Dirac field and the Proca field. The first step consists of…
Homotopy colimits and global observables in Abelian gauge theory
Marco Benini, Alexander Schenkel, Richard J. Szabo
We study chain complexes of field configurations and observables for Abelian gauge theory on contractible manifolds, and show that they can be extended to non-contractible manifold…
Locality in Abelian gauge theories over globally hyperbolic spacetimes
Marco Benini
The thesis investigates the locality axiom of general local covariance for Abelian gauge theories. Two models, Maxwell -forms (higher analogues of the electromagnetic vector pot…
