Nonassociative geometry in quasi-Hopf representation categories I: Bimodules and their internal homomorphisms
Gwendolyn E. Barnes, Alexander Schenkel, Richard J. Szabo
We systematically study noncommutative and nonassociative algebras A and their bimodules as algebras and bimodules internal to the representation category of a quasitriangular quas…
Differential cohomology and locally covariant quantum field theory
Christian Becker, Alexander Schenkel, Richard J. Szabo
We study differential cohomology on categories of globally hyperbolic Lorentzian manifolds. The Lorentzian metric allows us to define a natural transformation whose kernel generali…
Locally covariant quantum field theory with external sources
Christopher J. Fewster, Alexander Schenkel
We provide a detailed analysis of the classical and quantized theory of a multiplet of inhomogeneous Klein-Gordon fields, which couple to the spacetime metric and also to an extern…
