On the Space-Time Symmetries of Non-Commutative Gauge Theories
A. Iorio, T. Sykora
We study the space-time symmetries and transformation properties of the non-commutative U(1) gauge theory, by using Noether charges. We carry out our analysis by keeping an open vi…
Covariant Schwinger terms
C. Adam, C. Ekstrand, T. Sykora
There exist two versions of the covariant Schwinger term in the literature. They only differ by a sign. However, we shall show that this is an essential difference. We shall carefu…
Schwinger terms in 1+1 dimensions
Tomas Sykora
The two different approaches - Källen's and Brandt's methods - for the calculations of the Schwinger terms in the 1+1 dimensional Abelian and non-Abelian free current algebras are…
On the Point-Splitting Method of the Commutator Anomaly of the Gauss Law Operators
R. A. Bertlmann, Tomas Sykora
We analyze the generalized point-splitting method and Jo's result for the commutator anomaly. We find that certain classes of general regularization kernels satisfying integral con…
