Gauge Fields on Non-Commutative Spaces and Renormalization
arXiv:1402.5980 · doi:10.1002/prop.201400009
Abstract
Constructing renormalizable models on non-commutative spaces constitutes a big challenge. Only few examples of renormalizable theories are known, such as the scalar Grosse-Wulkenhaar model. Gauge fields are even more difficult, since new renormalization techniques are required which are compatible with the inherently non-local setting on the one hand, and also allow to properly treat the gauge symmetry on the other hand. In this proceeding (which is based on my talk given at the ``Workshop on Noncommutative Field Theory and Gravity'' in Corfu/Greece, September 8 -- 15, 2013), I focus on this last point and present new extensions to existing renormalization schemes (which are known to work for gauge field theories in commutative space) adapted to non-commutative Moyal space.
