Renormalization of Gauge Theories on NonCommutative Spaces 
Speaker:  Daniel Blaschke (Los Alamos National Laboratory, Theory Division) 
Abstract:  In order to explore the foundations of physics at very short distances, a mathematical framework describing a quantized version of spacetime geometry and quantum fields thereon is desired. One possible road to take, are the socalled noncommutative quantum field theories. Constructing renormalizable models on noncommutative spaces constitutes a big challenge. Only few examples of renormalizable theories are known, such as the scalar GrosseWulkenhaar model. Gauge fields are even more difficult, since new renormalization techniques are required which are compatible with the inherently nonlocal setting on the one hand, and also allow to properly treat the gauge symmetry on the other hand. In this talk I will focus on this last point and present new extensions to existing renormalization schemes (known to work for gauge field theor. in commutative space) adapted to noncomm Moyal space.
