BPHZ Renormalization in Configuration Space for the -Model
Steffen Pottel
Recent developments for BPHZ renormalization performed in configuration space are reviewed and applied to the model of a scalar quantum field with quartic self-interaction. An exte…
Normal Products and Zimmermann Identities in Configuration Space BPHZ Renormalization
Steffen Pottel
The notion of normal products, a generalization of Wick products, is derived with respect to BPHZ renormalization formulated entirely in configuration space. Inserted into time-ord…
Configuration Space BPHZ Renormalization on Analytic Spacetimes
Steffen Pottel
A configuration space version of BPHZ renormalization is proved in the realm of perturbative algebraic quantum field theory. All arguments are formulated entirely in configuration…
A BPHZ Theorem in Configuration Space
Steffen Pottel
The concept of BPHZ renormalization is translated into configuration space. After deriving the counterpart for the regularizing Taylor subtraction, a new version of Zimmermann's co…
