The energy-momentum tensor on noncommutative spaces - some pedagogical comments
A. Gerhold, J. Grimstrup, H. Grosse +3
We present the discussion of the energy-momentum tensor of the scalar - theory on a noncommutative space. The Noether procedure is performed at the operator level. Additionall…
Field Theory on the q-deformed Fuzzy Sphere I
Harald Grosse, John Madore, Harold Steinacker
We study the q-deformed fuzzy sphere, which is related to D-branes on SU(2) WZW models, for both real q and q a root of unity. We construct for both cases a differential calculus w…
Chiral Schwinger models without gauge anomalies
Harald Grosse, Edwin Langmann
We find a large class of quantum gauge models with massless fermions where the coupling to the gauge fields is not chirally symmetric and which nevertheless do not suffer from gaug…
Renormalization of noncommutative Yang-Mills theories: A simple example
Harald Grosse, Thomas Krajewski, Raimar Wulkenhaar
We prove by explicit calculation that Feynman graphs in noncommutative Yang-Mills theory made of repeated insertions into itself of arbitrarily many one-loop ghost propagator corre…
