Noncommutative gerbes and deformation quantization
Paolo Aschieri, Igor Bakovic, Branislav Jurco +1
We define noncommutative gerbes using the language of star products. Quantized twisted Poisson structures are discussed as an explicit realization in the sense of deformation quant…
Non-Abelian gauge theory on noncommutative spaces
Peter Schupp
We present a brief introduction to the construction of gauge theories on noncommutative spaces with star products. Particular emphasis is given to issues related to non-Abelian gau…
Noncommutative line bundle and Morita equivalence
Branislav Jurco, Peter Schupp, Julius Wess
Global properties of abelian noncommutative gauge theories based on -products which are deformation quantizations of arbitrary Poisson structures are studied. The consistenc…
Nonabelian noncommutative gauge fields and Seiberg-Witten map
Branislav Jurco, Peter Schupp, Julius Wess
Noncommutative gauge fields (similar to the type that arises in string theory with background B-fields) are constructed for arbitrary nonabelian gauge groups with the help of a map…
Cartan Calculus on Quantum Lie Algebras
Peter Schupp, Paul Watts, Bruno Zumino
A generalization of the differential geometry of forms and vector fields to the case of quantum Lie algebras is given. In an abstract formulation that incorporates many existing ex…
