Wess-Zumino Model in the Causal Approach
Dan Radu Grigore
The Wess-Zumino model is analysed in the framework of the causal approach of Epstein-Glaser. The condition of invariance with respect to supersymmetry transformations is similar to…

The Renormalization of the Non-Abelian Gauge Theories in the Causal Approach
Dan Radu Grigore
We consider the gauge invariance of the standard Yang-Mills model in the framework of the causal approach of Epstein-Glaser and Scharf and determine the generic form of the anomali…

Scale Invariance in the Causal Approach to Renormalization Theory
Dan Radu Grigore
The dilation invariance is studied in the framework of Epstein-Glaser approach to renormalization theory. Some analogues of the Callan-Symanzik equations are found and they are app…
