Renormalization in Quantum Field Theory: An Improved Rigorous Method
Silke Falk, Rainer Häußling, Florian Scheck
The perturbative construction of the S-matrix in the causal spacetime approach of Epstein and Glaser may be interpreted as a method of regularization for divergent Feynman diagrams…

Complete control of gauge parameter dependence in the Abelian Higgs model
Rainer Häußling, Stephan Kappel
We examine the dependence on all gauge parameters in the example of the Abelian Higgs model by applying a general algebraic method which roots in an extension of the usual Slavnov-…

Algebraic connections on parallel universes
R. Coquereaux, R. Haussling, F. Scheck
For any manifold , we introduce a $\ZZ $-graded differential algebra , which, in particular, is a bi-module over the associative algebra . We then introduce the c…
