Gauge fields on noncommutative geometries with curvature
Maja Buric, Harald Grosse, John Madore
It was shown recently that the lagrangian of the Grosse-Wulkenhaar model can be written as lagrangian of the scalar field propagating in a curved noncommutative space. In this inte…
IR-Singularities in Noncommutative Perturbative Dynamics?
J. M. Grimstrup, H. Grosse, L. Popp +4
We analyse the IR-singularities that appear in a noncommutative scalar quantum field theory on . We demonstrate with the help of the quadratic one-loop effective act…
Noncommutative spin-1/2 representations
J. M. Grimstrup, H. Grosse, E. Kraus +3
In this letter we apply the methods of our previous paper hep-th/0108045 to noncommutative fermions. We show that the fermions form a spin-1/2 representation of the Lorentz algebra…
Noncommutative Lorentz Symmetry and the Origin of the Seiberg-Witten Map
A. A. Bichl, J. M. Grimstrup, H. Grosse +4
We show that the noncommutative Yang-Mills field forms an irreducible representation of the (undeformed) Lie algebra of rigid translations, rotations and dilatations. The noncommut…
Novel Symmetry of Non-Einsteinian Gravity in Two Dimensions
H. Grosse, W. Kummer, P. Prešnajder +1
The integrability of -gravity with torsion in two dimensions is traced to an ultralocal dynamical symmetry of constraints and momenta in Hamiltonian phase space. It may be int…
