Power counting degree versus singular order in the Schwinger model
Andreas Aste, G"unter Scharf, Urs Walther
The importance of a rigorous definition of the singular degree of a distribution is demonstrated on the case of two-dimensional QED (Schwinger model). Correct mathematical treatmen…

Non-abelian gauge theories as a consequence of perturbative quantum gauge invariance
Andreas Aste, G"unter Scharf
We show for the case of interacting massless vector bosons, how the structure of Yang-Mills theories emerges automatically from a more fundamental concept, namely perturbative quan…
