Energy Momentum Tensor and Operator Product Expansion in Local Causal Perturbation Theory
Dirk Prange
We derive new examples for algebraic relations of interacting fields in local perturbative quantum field theory. The fundamental building blocks in this approach are time ordered p…
Lorentz Covariance in Epstein-Glaser Renormalization
Dirk Prange
We give explicit and inductive formulas for the construction of a Lorentz covariant renormalization in the EG approach. This automatically provides for a covariant BPHZ subtraction…
Lorentz Invariant Renormalization in Causal Perturbation Theory
K. Bresser, G. Pinter, D. Prange
In the framework of causal perturbation theory renormalization consists of the extension of distributions. We give the explicit form of a Lorentz invariant extension of a scalar di…
Causal Perturbation Theory and Differential Renormalization
Dirk Prange
In Causal Perturbation Theory the process of renormalization is precisely equivalent to the extension of time ordered distributions to coincident points. This is achieved by a modi…
